Underwired bikinis are some of the very best and most popular designs out there. For the longest time, designers have made these wonderful items of swimwear available to the public and they have always been some of the fasting selling items in the world of beach fashion. Why is it that the underwired versions of a bikini sell so much quicker and are more loved than any other counterpart in the world of swimwear? It's simple really, the profound effects on the shape of your figure and the sculpting effect it has on your body.

Origins Of The Underwired Bikini

For the longest time, swimwear didn't do much of anything for your figure. It was simply a two shoulder strap setup that offered a basic support, but nothing truly flattering or nothing that could reach the true potential your clothes had. Designers have since approached swimwear differently. Underwired bikinis were the ultimate result of these innovations. After years of perfecting the support of the straps and improving the way that bikini tops keep you secure, designers decided on a different approach. They began adding a thin strand of metal under the bra as a kind of shelf that would lift everything to the desired position. Combine this with the innovation of a separate and isolated pocket for this wire to sit securely in, a little like a draw string on your workout shorts but better, and suddenly underwired bikinis were able to give you the desired effect without any unwanted movement. Underwired bikinis have sky-rocketed in popularity because of these dual innovations of support and correct placement. Since then, every season that has ever passed has had more than its fair share of underwired bikinis, whether it be underwired versions of an existing designs or items that aren't even designed in a traditional soft cup.

Why Underwired?

Their ability to lift and shape cannot be beaten, even by padded bikinis, which is any design that comes with a soft foam or silicone padded area under the bust. This is the only other option for shaping outside of underwired bikinis, but it is no real option at all once you've tried the amazing effects of the latter and just how amazing the transformation can be. Underwired bikinis often come with other shaping options too, like the ability to add inserts to the cups for an even more custom fit and for extra volume. No other bikini designs cannot quite match these effects, and the best part is that they are not a specialist addition to your swimwear wardrobe.
