One piece vs bikini: which should you choose?
A one piece swimsuit covers the torso and stays put for swimming and active days. A bikini shows more skin, gives fewer tan lines and makes bathroom breaks easier. Shop one piece swimsuits and bikini sets.
Are one pieces more flattering?
Both can be flattering. Cut out, high leg and ruched one pieces shape the body, while high waisted bikinis give coverage with a two piece look. See high waisted bikinis.
Swimsuit vs cover up
A swimsuit is for the water. A cover up is a light dress, sarong or set worn over it at the beach or pool. See cover ups.
Pink, black and printed swimsuits
Black is slimming and classic, pink and bright colors pop against a tan, and prints hide texture. Browse both collections by color.
