A one-piece bathing suit with a high neckline is one of the best options for women who want to minimize a large bust. It gives you coverage and creates a more proportionate silhouette, as the eye isn't drawn only to the bust area. Skip those with a keyhole or low dip at the front, as these don't provide enough coverage.
A one-piece bathing suit with an empire waist or detailing such as ruching can draw the attention away from your chest and direct it to the intricate, interesting details on your suit, which can make all the difference in the look of the suit.
You can wear a two-piece bathing suit even if you have a large chest, as long as you choose the right one. A flimsy triangle bikini or bandeau top just doesn't work for you. If you want to wear a bikini, opt for one with thicker straps and a supportive underwire bra top. The underwire bra lifts and secures your bust and prevents your top from falling out of place.
You don't have to shy away from a halter-neck style just because you have a larger bust; it can work as long as the top has thicker straps to give you support, and the top itself is large enough to cover your chest fully. Also, opt for a solid color -- preferably dark, like black or navy -- to minimize your large chest.
