You should know one thing; at Swimwear World we promise never, ever to be boring! In recent years, one piece swimwear has been targeted to older generations, resulting in dowdy designs and frumpy suits. People have completely missed the fact that it can be made super sexy and fashionable for younger ladies as well! We are on a major mission to bring the one piece designer swimsuit back in a brand new avatar. To fulfill this mission, we have partnered with several prominent luxury swimwear brands who strive to create sassy designer one pieces which can make any girl feel like a golden goddess!

One piece swimwear can be a lot of things: fun with animal print, flirty with ruffles, sexy with bold cut outs or fancy with spectacular gold hardware. We reckon it is one of the best styles to accentuate your best features and hide your flaws. What’s not to love? Regardless of your body shape or style preference, you are bound to find something in our store which fits the bill so take your pick and let your designer swimsuit do the rest of the talking. Who said the one piece is dead? In fact, it is just coming of age!
