The UK Swimwear A - Z of Swimwear

Asymmetric - A term which could apply to any swimwear which is not the same on both sides. Most commonly refers to swimwear with a strap over only one shoulder leaving the other side of the garment strapless.

Bandeau - A bandeau is usually a strapless item of swimwear but can often come with detachable straps (see also 'Convertible Swimsuit or Bikini'). The term bandeau can be used to describe any item of swimwear with a single band of fabric fitting around the bust. A bandeau is usually moulded to provide support but can also be constructed from soft, elasticated fabric. It is possible to have a bandeau bikini, bandeau swimsuit or even a bandeau sundress.

Banded Bottoms - Bikini bottoms which have a wide band around the top edge, often in a contrasting colour but not necessarily. This style is also referred to as fold top bikini bottoms. These kind of bikini bottoms create the illusion of a flatter tummy and offers a little more coverage than the regular kind. The term banded bikini bottoms has also been used by designers to describe briefs which, instead of having one piece of material wrapped over each hip, they have several straps which expose the skin in between.

Banded Halter-Neck (Or Banded Halter Top) - A halter-necked swimwear garment which has a wide elastic band under the bust for added support. This is a design feature most commonly found in bikinis but could also apply to a sundress.

Bandini - A strapless bikini or two-piece swimsuit. The top of which is just like a band of material around the chest- see also 'Bandeau Bikini'.

Bikini - A bikini is a two-piece swimwear set, with briefs and a bra-like top to cover the bust. Just like a knickers and bra set that is specifically made for swimming or sunbathing in. Perfect for maximum tanning and for staying cool. There are many variations in style such as a 'Bandeau Bikini' or 'Halterneck Bikini'.

Blouson - A blouson effect is created by loose material handing down from the bust which is gathered around the waist or hips - like a blouse. Can refer to a Blouson Swimsuit or Blouson Tankini. A flattering design feature which alters your silhouette and hides any excess baggage you may be carrying around the midriff area.

Board Shorts - An item of men's swimwear that is very similar in style to 'Water Shorts' the main differences being that board shorts typically have a drawstring around the waist, water shorts have a plain waistband. Water shorts also tend to be shorter in length than board shorts.

Boho or Boho Chic - If you're not sure how to go about creating the boho look, think 1970's, festivals, in particular, Woodstock or Coachella. The boho look has been a strong trend for a few years now and is still as hot as ever on the 2018 catwalks. Key motifs of the boho style are floral embroidery, beads, paisley, floaty fabrics and tie-dye.

Bows - Bows can be a design feature that is appliqued or sewn on as in a bow front bikini. Bows can also be self-tied as in a 'Tie-Side Bikini Bottom'. When we say self tied, we mean that the art of tying the bikini straps creates a bow rather than a bikini that ties itself!

Boy Shorts - Not an item of boy's swimwear, as you might think. Rather, the term refers to ladies bikini bottoms which are cut in a boyish style. Think cute rather than masculine!

Bra Top - A bra style bikini top featuring a strap over each shoulder. Exactly like a bra only made from quick drying, stretch fabric specially designed for swimming.

Brazilian - A Brazilian is a word used to describe bikini bottoms cut in a particular style. Brazilian bikini briefs curve outwards like a Y shape, not as revealing as a thong but showing more cheek than a normal, full brief. The Brazilian is also a low rise and is the second most revealing brief after a thong.

Bustier - A bustier bikini top is one that is very fitted around the ribcage creating a lot of structure in the bust area.

Burkini - A burkini (sometimes spelt burquini) offers full body coverage for modest bathing or swimming. Originally designed for women who wish to respect their Islamic faith whilst on the beach. Be careful wearing one of these items in France, where they were banned, causing a great deal of international controversy.

Chevron - A symmetrical pattern created by diagonal lines meeting at a centre line.Chevron patterns are particularly flattering when the centre line lies downwards across the middle of the tummy or breasts creating a minimising effect.

Color Block - A geometric pattern created by combining two or three contrasting colours. Can be a particularly flattering effect when used to accentuate the waist area.

Constructed Shelf Bra - Moulded foam cups which can be hidden within the structure of a bikini top or swimsuit. Usually combined with a soft, wide band under the breasts to offer maximum support.

Contoured Top - A bikini or swimsuit with seams sewn in such a way that it creates structure in the garment to enhance and support the bust.

Control Top - A bikini or swimsuit design made using hi-tech materials which provide support and streamline your figure. A big hit with young mums!

Contemporary - Designs with an innovative and modern cut or design. Often used in the swimwear fashion industry to describe ranges updated by season. Whn a swimsuit is cut in such a classic shape, the only thing it needs to bring it up to date with this season's trends is a colour change.

Convertible Dress/Skirt - A versatile beach cover-up which can be worn in a number of ways. For example, a skirt that can easily be turned into a dress or maybe a bandeau dress which can also be worn strapless.

Convertible Swimsuit or Bikini - If undecided between a bandeau bikini or a strapped one, we recommend a convertible bikini or swimsuit. Convertible swimsuits and bikinis come with a detachable strap which can be removed altogether. Convertible designs are usually indistinguishable from conventional swimwear. The difference is that there will be two small hooks at the top of each cup to which the straps can be attached.

Cookie Pads - Small foam pads which sit between two layers of material in the cups of a swimwear garment. Designed to offer a little modesty around the nipple area.

Cover Up or Beach Cover Up - A super versatile holiday must-have garment which can easily be thrown on over swimwear, either to escape from the sun or to carry you effortlessly from the beach to the bar.

Cross Back - A cross back is a sexy design feature which can also offer additional support in the bust and waist areas. A popular design feature with swimmers due to the staying power the cross back swimsuit offers when swimming at speed.

Cutout - As the name suggests, a one-piece swimwear garment which has the sides cut out to expose the waist whilst giving a little more coverage than a bikini. Also sometimes referred to as a 'Monokini'.

Embellished - Any decoration which is not printed on the fabric but attached to the garment afterwards. Can be bows, beads, sequins, crystals, diamante, embroidery or any combination of these elements.

Fauxkini - A phrase coined by the brand Miraclesuit, specialists in shaping and tummy control swimwear. The term Fauxkini is used to describe a two-piece swimsuit that looks like a one piece. A Fauxkini is designed to be more revealing than a regular swimsuit but more flattering than a two-piece. More commonly known as a 'Tankini'.

Flounce - A long frill most commonly applied to the top edge of any swimwear or beachwear. A flounce is an elegant way to enhance smaller breasts.

Fringe - A decorative linear embellishment made from cut lengths of fabric or strings of beads. The epitome of boho style and a gorgeous way to finish off the edges of a kimono or beach cover-up.

Frong - A swimsuit which has such a high leg that the front is almost like a thong.

Full Bottom - A bikini or swimsuit which offers more coverage around the bottom and lower hip area. Most swimwear has a full bottom unless it is marked otherwise, as having a 'Brazilian' or alternative type bottom.

Full Cut Top - Also referred to as a full cut bra bikini top. A bikini top which offers more coverage around the chest area. Ideal for women who have a tendency to burn their delicate decolletage area in the sun.

Full Piece Bathing Suit - An alternative term to describe a one-piece swimsuit, bathing suit or swimming costume.

Gusset - The piece of fabric which covers the crotch area of a swimming costume.

Halter Neck - Halter neck swimwear has a single strap that fits around the back of the neck, instead of the two shoulder straps of a traditional bra-top. The ends meet at the nape of the neck and can be fastened with a clasp, self-tied into a bow, or fastened at the cup with no fixtures on the neck. They are great for leaving the arms, shoulders, and back uncovered. The effect is that the breasts are pulled together rather than up which enhances your cleavage and creates a classy look.

High Waist - A high waist bikini is perfect for achieving a vintage look. High waist bikinis come in all shapes and sizes with some coming up to the belly button. As well as being incredibly stylish, a high waist also offers a little more coverage and control than a standard bikini bottom.

Hipster Bottom - Bikini bottoms that sit low on the hips for a cute, 60's retro look.

Hot Shorts - More commonly knows as hot pants which are teeny weeny shorts cut just below the bum cheeks - hot! See also 'Boy Shorts'.

Keyhole - A teardrop shape cutout which can occur at the neckline or to accentuate a particularly attractive part of the body such as the lower back or cleavage.

Light Fastness - A fabric's ability to hold it's colour upon exposure to sunlight. Sunlight along with chlorine are the two things most likely to fade swimwear. Swimsuit fabric is especially developed to ensure that it can stand up to the harsh suns rays.

Lycra - LYCRA ® is the magic ingredient in most of the material used in swimwear, which provides elasticity and support to swimwear garments. Also known as 'Spandex'.

Mastectomy Swimwear - Swimwear designed especially for women who have undergone a mastectomy operation. Both mastectomy bikinis and mastectomy swimsuits exist and most designs are ideal for single or double mastectomy patients.

Mitred Seam - A term used to describe a swimsuit made from fabric featuring a diagonal pattern or stripes which has a centre seam. The seam down the middle of the garment creates a very flattering effect, in much the same way as a 'Chevron'. A treatment usually given to the seam down the centre of a one-piece swimsuit or the cups of a triangle bikini.

Moderate Bottom Bikini bottoms which strike the perfect balance between coverage and exposure.

Moulded Cup - A moulded cup bikini is part way between a soft cup and a padded cup. They are a preformed cup that is semi-firm but not dense with foam padding. The material has a thin layer of padding built in for rigidity. This means it can hold its own shape but doesn't add size to your bust. Great for support and often found in underwired tops.

Monokini - Also referred to as a 'Cutout' swimsuit. Basically, a one-piece bathing suit which is designed to look like a bikini joined in the middle across the tummy area.

One-Piece - An alternative name for a swimsuit that is more commonly used by our friends 'over the pond' in America. A one piece can include swimming costumes with cutouts too, as long as the suit is made from one single piece of material. On the continent this kind of swimwear garment might be referred to as a 'Maillot'.

Pareo - A pareo is a simple oblong shape of fabric. It is usually the size of a beach towel or a bit larger. A pareo can be wrapped around the body in many configurations. These include the following: A long bandeau dress, long skirt, doubled over as a short skirt, scarf, headdress, or fashioned into a sling bag for odds and ends.

Ruffles - Ruffles are short frills that are used in swimwear design as a crafty way of creating curves that slimmer women may be lacking. To create the illusion of a fuller bust for example, or more curvy hips.

This is particularly helpful if you require larger bikini bottoms than bikini tops or if you require DD+ bikinis. The majority of bikinis are supplied by swimwear designers in a C/D cup as this is the most popular cup size.

Shelf Bra - Used to describe the hidden support concealed within a swimsuit or bikini which is designed to lift and give shape to the bust.

Skirtini - Although it is an adaptation of the word "bikini" it is any skirted swimwear. These are usually a swimsuit or sometimes a two-piece, that has a skirt attached to the hem of the brief. They are often short and decorative like a tutu, rather than practical. But both are available.

Sundress - A sundress is a dress which is designed to be worn in warm weather. Depending on the designer, it is often intended for wearing on its own but some are for wearing over swimwear.

A sundress can be informal or casual and is usually made from a lightweight, quick drying fabric.

Swim Dress - Very much like a skirtini, a swim dress is a swimsuit with a skirt built into the design. But these use a longer skirt, and look more like a sundress. This is better understood as a dress you can swim in. It has a built-in brief so you don't become exposed as the skirt moves with the water.

Swim Shorts - With reference to ladies swim shorts, these are a popular alternative to classic bikini bottoms. A popular choice for women who like to play beach sports or could also be suitable attire for walking around town.

Triangle Bikini - The simplest form of bikini top which is made up of two triangles to cover the breasts. Triangle bikinis often have flat seams underneath which gives a minimal, retro look or can be gathered along the lower seam.

Tricot - Very fine knit material having high stretch properties. The most common fabric used in swimwear.

Trikini - Can also be called a 'Monokini' or a 'Cutout'. Basically, a bikini which has the top and bottom joined together, usually by a strip of material down the centre of the back and/or front of the garment. Trikinis are an excellent choice for those who want the bare skin feel of wearing a bikini but may not have the confidence to wear one.

Tummy Control Swimwear - Yes, this IS a thing and it is as miraculous as it may sound! In fact, it is such a hot topic that we wrote a complete guide to tummy control swimwear which is designed to help you find the perfect swimsuit that will make you look your best on the beach.

Underwire - A thin, curved metal strip which is concealed within the seam of a swimwear garment to give shape and support under the bust. Exactly the same as the underwire you would find in a bra.

V-Wire Bandeau - A V-Wire is a sexy, daring design feature incorporated into some bandeau bikinis or swimsuits which looks as though it might reveal a little more cleavage than a regular bandeau. In actual fact, it doesn't due to the shadow it creates. A V-Wire is sometimes also referred to as a U-Wire depending if it is curved at the bottom or comes to a point.

V-Kini - Think 1980's glamour. V-Kini bikini bottoms have a wide band over each hip which meet to form a V shape in the middle of the lower abdomen.

Water Shorts - An item of men's swimwear. Loose fitting shorts made from quick-dry fabric which are specifically designed for swimming in.

Wet Suit - Swimwear which covers the whole body and is made from thick, rubbery material. A wet-suit is designed to trap a layer of water next to the skin which acts as an insulating layer. Commonly worn by divers or watersports enthusiasts.
