A tankini is a two-piece swimsuit--it gives you the flexible sizing of a bikini, but with a longer top that provides more tummy coverage. The tankini top is a favorite for a lotta reasons, but coverage and comfort take the cake. These tops offer more support and comfort for larger busts, and the same level of coverage as a one-piece but with a little more flexibility. Tankini swimsuits first arrived on the beach scene in the late 1990s. Anne Cole, the mastermind behind this game-changing swimsuit, introduced tankinis as a happy medium--something that wasn't as revealing as a bikini, but still provided the coverage most women were wanting at the time. Since then, tankini swimsuits have evolved to suit all kinds of beach days, from sport-filled to casual and everything in between.
