10 Swimsuits Anyone With Small Boobs Should Buy Immediately

If you have a smaller bust size, shopping for swimsuits may feel like a challenge every summer. It’s not that you won’t feel hot in your suit (because duh—Of course you will!) but finding one that fits in all the right ways can be more of a challenge. But don’t fret. I’ve found the best swimsuits for small busts that will fit you perfectly and won’t move around throughout the day, whether you’re lounging around by the pool or partaking in some more active beach-side activities.

There are actually many swimsuit styles that are made specifically to look amazing on those with smaller breasts, no matter what style you’re into right now. Generally, opting for a bikini or one-piece that comes with padding or underwire will add more lift if that’s what you’re looking for, while more daring styles—like those suits that are covered in cutouts or options with a one-shoulder design—are guaranteed to highlight your natural cup size to perfection. Simple string bikinis, for instance, are super on-trend for summer 2021 and they look fab on you precisely because you don’t necessarily always need a ton of support.

The options are (nearly) endless. Abercrombie & Fitch, for instance, sells a pastel green seersucker bikini that comes with puffed sleeves for some seriously romantic vibes, and Frankies Bikinis offers a floral one-piece with ties all down the side. Andie Swim even makes the cutest strapless suit that stays in place all day no matter what activities you may be taking part in at the beach.

Ready to shop? Read on to see ten of the best swimsuits for smaller busts. You’re going to look so good in all of these.

Dalia Top + Ashley Bikini Bottoms

If you thought that bikinis with underwire were designed for your friends with bigger busts, think again. This pink pick from Onia is great if you have smaller boobs because it offers support and features a cutout in the middle that will keep the cups from gaping at the top or sides. The matching bottoms really complete this Elle Woods-inspired ‘fit.
