Looking for the best bikinis for small boobs? As much as the gals with DD+ cups struggle to find good swimwear, those of us with lil’ boobies have a bit of a task, too. If you need some inspo, cast your mind back to a ‘90s Kate Moss wearing those iconic minimalist triangle styles or take a leaf out of Iris Law and Hailey Bieber’s books – small-busted gals can really rock those skimpy, tie-ups like nobody else!

Shop the best bikinis for small boobs

But if you’re actually here because you want to make a little more of what you’ve got going on under your beach cover-up, or need a bit of oomph/push-up/hiking, we’ve got you. From padded and underwired styles to clever moulded shapes and stretchy, wireless options, there’s a whole host of bikini tops out there just waiting to create some magic.

How to choose a bikini for small boobs

Gone are the days of desperately stuffing triangle tops with socks—now it’s all about finding swimwear that flatters, fits, and actually feels good to wear. We’re also aware that it’s not just petite people that have small boobs, which is why our round-up includes bikinis available in sizes XS-4XL.

If you’re after a lift, look for padded styles or bikini tops with underwired cups and halter-necks that hike and squish to give the illusion of more cleavage. If you just want a top that won’t gape every time you move, think chic bandeaus, tops that mould to your shape and clever ruching . Of course, style is personal, and what makes one person feel sexy and supported might not do the same for another. But to help you out, you’ll find handy size guides, special feature notes and padding deets under each pick.

So whether you’re sunbathing in Ibiza or just vibing in your garden with an iced coffee, keep scrolling for Cosmo’s pick of the best bikinis for small boobs that’ll leave you feeling like that girl...
