If you want to conceal your belly yet stay as flexible as possible, tankinis are your best bet. They are halfway between a swimsuit and a bikini. This two-piece swimwear consists of a pair of panties – which in the case of plus-size swimwear often comes in the form of panties with a wide waistband and a lower cut on the leg – and a top. The top, which goes all the way to the waistband of the panties, usually has a fairly loose cut and falls gently over your curves. And it’s so practical too: when you’re sunbathing, you can simply pull the top up a little, and it still covers your belly as you walk down to the water.
