I'm not sure who we should thank for putting the one-piece swimsuits back on the fashion map (it could be Madonna or Lady Gaga with their leotards love), but the trend is here to stay for at least few seasons. Besides updating the one-piece shapes with trendier silhouettes, designers these days are inventive with prints, accessories and details - all contributing to the dressy sophisticated looking and body-friendly pieces. My favorite picks below:
