We’re getting ready for a tropical beach holiday! After a couple of years of staying in, more and more borders have opened and we can start ticking off items from our beach bucket list. Of course, we want to look chic in our swimsuits wherever we’re sunbathing.
For women with bigger busts, opting for one-pieces that come with underwire is a sure-fire way to find swimwear that offers support — but finding them can prove challenging. There’s still a lot to be improved in the plus-size department when it comes to swimwear but things are thankfully getting better.

Here are 8 of the best plus-size one-pieces with underwire from our favourite curve fashion stores, including Simply Be, Curvy Kate, ASOS, Next, and more.
