What type of swimsuit is best for small bust?
To get more insights, we asked Sarah Landman, CEO of swimsuit brand Solid & Striped, to share her tips for choosing the best swimsuits for a small bust. “Look for triangle and halter tops, as these tend to fit a small bust best,” says Landman. Of course you can go for those more structured types if you like the style, but they typically leave you more exposed due to all the extra space. Plus, a perk of having smaller boobs is that you don’t need as much support, “which can be a big limitation when shopping for swim,” says Landman. And if you do prefer your swimsuits give you a lift, Landman recommends looking for swimsuits with light padding, of course, but also textured fabrics to give the illusion of more volume at the bust.
