Swimwear Fitting Guide

70% of women in the UK regularly wear the wrong size bra. If you're wearing an incorrectly sized bra, it's highly likely you'll pick incorrectly sized swimwear too. Poorly fitting swimwear can not only result in unsightly lumps and bumps but can also cause discomfort and back pain. If you are about to invest in some lovely new swimwear for your holiday, isn't worth making sure you are wearing the correct size? It only takes a few minutes to check your measurements and the result will be a smooth silhouette and comfort on the beach.

The Swimwear Size Guide

Most commonly, women wear a band size that is too big and a cup size that is too small. This may feel comfortable around the ribs but can lead to tension in the upper back and bad posture. Many high street stores offer a swimwear fitting service. Did you know that measuring yourself for swimwear is something you can quite easily do yourself? If you are unsure how to measure yourself properly for swimwear, follow our simple three-step guide to get an accurate, reliable measurement. It doesn't matter if you are buying a swimsuit, bikini or tankini, the principle is exactly the same.

Step 1: Measure Your Back Size

Take a soft tape measure and measure around your back and under your bust. Make sure that the tape sits parallel to the floor all the way around and feels secure. This will give you an accurate measurement across your back. Find your number, in either inches or centimetres and write it down. Be sure to round everything up to the nearest whole number.

Step 2: Measure Your Cup Size

Whilst wearing a non-padded bra, or in the nude, stand upright with your arms at your side and measure the fullest part of your bust. Make sure the measuring tape is parallel with the ground and not lose or too tight. Measure around your back as before and find your number, again round it up.

Step 3: Calculate Your Cup Size
