A guide to the best swimwear for large busts

Supportive swimwear? No problem.

If you're blessed in the chest department, you'll know all too well how hard it is to find the best swimwear for large busts. Without a doubt, you need something supportive that'll keep you in place when you're going for a swim - and, yep, even when you're lying down on a sunbed. The struggle is all too real.

You've probably come to realise that a standard string bikini isn't going to cut it if you have big boobs. With the wrong level of support, you're more likely to experience discomfort, back pain - or even worse, a dreaded wardrobe malfunction that you'd much, much rather avoid.

There's loads of swimwear on the market now, from tummy control swimwear to shapewear swimsuits. But, when you have a bigger bust, this is something you definitely have to consider while you look for a new bikini. Think thicker straps, halter neck or racerback designs and underwiring for plenty of support.

Customer review: "I've got to say after ordering 6 different swimsuits from multiple places I was a bit sceptical about ordering this one because non of the other felt like they would keep everything covered whilst at a waterpark on holiday! However, I'm so glad I ordered this one as it was perfect! Kept everything where it was supposed to be and felt so secure, easily one of my best buys, the colour is so nice and the tummy control works wonders, the cross over straps were so easy to use/adjust and helped with supporting the chest. I'm a size 12-14, 36DD bust and ordered a size large as I found most other costumes were to small for my chest, but this was perfect!"
