25 Best Bikinis For Small Boobs & Small Busts 2025

As a proud member of the itty bitty committee, every summer has me searching for the best bikinis for small boobs. Sure, by now I’ve found a fair few styles that are tried and true, but what girl doesn’t look forward to adding some new one-piece swimsuits and bikinis to their collection before a holiday? I know my packing list isn’t complete with at least one new swimwear item to show off at the beach.

That said, I’ve a list of criteria that needs to be met when shopping – and I know from my friends who are tasked every year with finding the best bikinis for big busts that it is just as difficult for them. Proper support is an absolute must, but you also want a little lift and a cute colour. Not many swimwear brands have perfected that recipe, but together, best believe we’ve sniffed out the ones that do. And of course a lot of them are tried and tested by team GLAMOUR so you can guarantee these swimwear styles are the best of the best.

From cupped push-up bikini to slinky bandeau bikini styles or the much-loved triangle bikini (a small chest hero) there’s a variety of styles to create the ultimate beach babe look – especially when it comes to those who have smaller boobs.

A trick adopted in recent years by influencers and celebs alike, which I love, is turning triangle bikinis upside down to create some oomph without any gaping. You simply flip the top upside down and cross over the straps in such a way that holds your boobs more securely and often gives them a lil push up, too. A top tip to take on your next holiday to make that new bikini purchase a two-for-one buy.

If extra padding isn’t your bag, then underwire bikinis are another favourite style of mine. They enforce structure and shape to your bust, whilst giving the girls that natural lift, support and coverage all in one. Mango, ASOS and H&M are great high street hot spots for this kind of style, along with Marysia is you’re looking for a designer bikini.

As a B/C cup girly who spent her teen years spending too much money on maximum push-up bras in an effort to feel more confident, I’ve gone through a lot of trial and error to find the style of bikini that not only flatters but works with my chest. And for me, this is the key tio knowing what actualler suits my smaller chest – as we know, no ones boobs are the same, so like a bra, it’s best to try on a whole variety of bikini styles to add to your swimwear edit.

With my all-time favourties in mind, I’ve rounded up a variety of styles that manage to avoid gaping, bunching up and sagging as much as possible, but as mentioned, everybody is different and your personal preferences may differ from mine.
