Haparai swimwear has cute swimsuit designs for a boyish figure. If you lack curves and have more of a tom boy figure the Hapari style looks cute. They sell bottoms, tankinis, bikinis, and tops as separates. The most popular right now is the Bora Bora ruffle bikini top. I found this featured at Active Wear USA.
This top comes in white as well as this fun colorful print. While not the sexiest thing in the world, the bikini is quite flattering on a woman with a boyish frame. When you have an athletic body that lacks curves then a quite frilly top can be flattering. As shown here, it adds a feminine flounce to this girls natural athletic look. It’s cute, frolicking and fun. The ruffled top can be paired nicely with a solid color bikini bottom.
