Every four or five years I take the plunge and buy a new bathing suit. It gets harder and harder to find something with coverage that also fits and looks good and this year I am loving the suits by Marysia. She is a former ballet dancer and surfer and she's clearly filling a void for sophisticated suits that we can all wear that cover and don't look dated in two years. They are expensive but if you use it for a few years it works.
She's all the rage and her suits can be found in many stores on the web and beyond. Here are some that I am loving (I don't do bikinis anymore):
Others are starting to copy her signature scalloped trim like J Crew and Kate Spade. But she has great style.
