From one small-chested woman to another, I know how hard it can be to find the perfect swimsuit that flatters smaller boobs. While there are many brands that create amazing swimwear, not all of them look good on small-busted gals. So, if you’re struggling to find what you need, take a look at our guide to 30 chic swimsuits for small busts.

While you can always turn to a padded bikini, there are many other factors that can make you feel more confident in your frame, ranging from different styles, cuts, and designs that can enhance your overall mood and appearance. In this round-up, we’ll share our favorite bikinis and one-piece swimsuits to enhance your assets, but before that, let’s talk a little about what to look for when choosing a swimsuit.

What To Look For In Swimsuits For A Small Bust

With the rise of K-pop and the move towards a more body-positive, more accepting world of all bodies, we’ve also seen more models and celebrities with small chests, such as Lily Collins and Cindy Kimberly flaunt their natural bodies.

These women have made it cool to wear whatever bikini style you want with a small bust, and the connotation of having a small chest isn’t necessarily a bad thing. However, if you want to create the illusion of a bigger bosom or find a swimsuit that flatters your body type to its fullest potential, here are a few tips.

1. Padding

Padding is the most obvious thing to look for if you want to add a cup size or two. Opt for understated styles with removable padding if you’re looking for a small lift, or go for swimsuits with pronounced push-up inserts for a more dramatic effect.

2. Underwire Support

Underwire swimsuits are particularly flattering, as they lift up your girls and make them appear slightly fuller. 

3. Ruffles, Embellishments & Ruching

If you have a small chest, swimsuits with added drama are your friend, as they create extra volume that’s flattering on a smaller figure. The embellishments can be anywhere – directly on the chest or on the shoulders.

Now, with these tips in mind, let’s jump into our favorite swimsuits for small boobs, ranging from push-up styles to chic bandeau tops and one-piece swimsuits with plunging necklines. There’s a swimsuit for every personal style, we can promise you that!
