Halter necks and deep V's are your friends.

Yes—those are the styles that flatter broad shoulders best. Anything that draws the eye inward and downward balances your frame.

Halter tops visually break up the shoulder line, and the straps pulling toward the center create a narrowing effect. Deep V-necks do the same thing—they lead the eye down, not out. Off-the-shoulder and one-shoulder styles can work too, but they’re more hit-or-miss.

What to skip: high necks (mock necks, crew cuts), thick straps that sit right on the edge of your shoulders, and anything with heavy detailing on the shoulders like ruffles or epaulets. Those just make your shoulders look wider.

A good trick: pick a swimsuit with a darker top and a brighter or patterned bottom. That shifts visual weight downward and balances your proportions.
