Two piece tankinis are very fashionable right now. They have bottoms that are not cut as high as most bikinis and a top that covers most of the midriff. Boy cut shorts are also popular, with either a bikini or tankini top. A lot of styles are mixed and matched now, so you can buy multiple pieces.
Girls bathing suits come in full, tankini, and bikini. These styles are consistently available every year. Tankini's are the most popular because they offer style with ease of use.
Teens like two-piece's, with optional wraps/covers for the bottom. However, one-piece's are coming back, with cute cut-outs on side or belly, backless(except strap), cute prints, and are typically figure-flattering.
Oddly enough think back to when you wore bathing suits and it will probably be back in style. The suits from the 30's and 50's are more popular. Something in a bikini style from that era.
