It's been mentioned on so many different swimsuits & bikinis from Roidal this season. The whole collection has been designed with Minimalism in mind. There's nothing wasted on Sindi or any other bikini in their collection. The simple, unadorned bikini bottoms serve to highlight the elegant twisting material of the cups. This all makes a beautiful & attractive contrast. The ruched cups also have a second purpose. They highlight your curves & bust, which lengthens your figure & gives you a more defined shape. The Roidal Sindi is an onlookers bikini, & swimwear for the elegant woman, all at the same time.
