When shopping for bathing suits, finding the perfect fit is crucial. It can be especially difficult to find the best swimsuits for small busts, but we have some great tips and tricks to share. According to Tiffany Rivers, co-founder of Hermoza Swimwear, the key is to look for flattering and confidence-boosting silhouettes. “Padding and built-in bra features are your best friends,” she says. “Adjustable straps are crucial for getting the perfect fit and ensuring you get the lift and support you need,” Rivers continues. “Additionally, swimsuits with underwire provide extra support and shaping, which can make a big difference in how your bust looks.” Rivers emphasizes that bikinis and one-pieces are both viable options; coverage is a matter of preference. What’s most important, she says, is the neckline. And speaking from personal experience, we can agree.
Now that Memorial Day is over and summer is officially here, it’s the perfect time to refresh your swimwear collection with pieces that offer both support and style. Whether you’re gearing up for a tropical vacation or simply planning to enjoy some sun at the pool, you deserve to feel good in whatever you wear—even if it requires an optical illusion. Below, find 25 fantastic swimsuit options for small chests.
