29 bikinis for small boobs according to someone with a B-cup bust

Every year, I restart my quest for the best bikinis for small boobs. I'm a B-cup, and while my wardrobe holds its fair share of epic bikinis and one piece swimsuits/bathing suits that I love to wear year after year, I'm practically incapable of booking a holiday without treating myself to something new.

For the flatter-chested among us, shopping the best swimwear brands admittedly isn't too much of a gripe. Sourcing the best bikinis for big busts is undeniably much harder (as tricky as finding bras for big boobs), and my bigger-chested friends often find it difficult to find something with ample coverage, support and lift.

When it comes to bikinis for small chested people, however, there is choice aplenty. I'm grateful that I can be a lot more experimental with shapes, cuts and styles – from push-up bra style bikinis to skimpy bandeaus and wrap-around, tie-up options (without worrying about any *ahem* fall-out). Luckily, these are exactly the shapes the SS24 runways are favouring, just look to Oséree, Adriana Degreas, Hunza G and Missoni.

Of course, you might not feel super confident about having smaller boobs. In which case, your quest for the most flattering bikinis for small busts may be powered by a desire for a little more lift and cleavage. Relatable? I've got you.

Small bust swimwear that's flattering is a thing, and many of the styles down below will serve up welcome oomph without any gaping. Wearing triangle bikinis upside down is worth particular note for the new season, with lots of influencers and celebrities adopting the style hack for a strappy alternative to the signature look. You simply flip the top upside down and cross over the straps in such a way that your boobs will be pulled closer together. Cleavage: incoming.

Boux Avenue have a few different push-up options – namely this butterfly print design which has padded cups for that larger bust illusion – while, elsewhere, underwired bikinis for small boobs (for that all-important support and coverage) can be found via Mango, ASOS and H&M.

How we chose the best bikinis for small boobs

As aforementioned, I am a B-cup girly who has tried enough bikinis to know which silhouettes work and which ones definitely don't. Ahead you'll find a variety of styles that manage to avoid gaping, bunching up and sagging as much as possible, but as always, every body is different and your personal preferences may differ from mine. To help aid your decisions, though, you'll find size ranges and padding information listed beneath each product.
