I *LOVE* IT
Color is darker and richer in person (which I love). The shape is flattering, versatile, and classic. Good quality material and lined! Win-win-win. I wear a 2-4 and I'm very glad I went with a 6/S. I found the bikini in 6/S fit me just right! Hope that helps girlies similar to myself. Will be buying more bikinis from Vitamin A for sure!
