Identify your body type and then choose a silhouette to flatter it best. For example, if you have a smaller bust, a padded style, ruffles, or horizontal stripes will add volume on top. Also, triangle bikini tops really look best on smaller-busted women.
If you’re busty, choose a supportive style with a halter neckline that has a band under the bust and a wider strap that ties behind your neck; a one piece with a V-neckline; or a bra-sized swimsuit with built-in underwire.
To minimize your booty, sometimes a lower-rise cut or rings on the sides give the illusion of smaller hips. Avoid anything too tight—elastic that digs into the skin makes you look bigger. Another trick is to wear a darker color bottom with a lighter color top—dark always minimizes. If you really want hip coverage, go for a sash bottom or a boy short. And to completely distract from your hips, go for a one piece with a plunging V-neck.
