If there’s one article of summer clothing you can never have too many of floating around in your closet, it’s undeniably the swimsuit. There’s just no resisting all the incredibly cute styles out there that lend themselves to swoon-worthy poolside outfits, beach day ensembles and summer party looks. And while bikinis, tankinis and swim dresses are all viable summertime options, nothing quite beats the classic silhouette of a gorgeous one-piece. When the temperatures are hot, you can consider plus-size one-piece swimsuits the perfect base for any outfit—whether you’re just hanging out in your backyard or hopping from pool party to pool party.

If you’ve only ever considered your swimsuits perfect for, well, swimming, have we got some news for you. Obviously one-piece swimsuits are great for lounging by the pool or relaxing in the sand, but they also work as a starter piece for hot summer ensembles. (!!!) After all, one-piece bathing suits are basically bodysuits, so why not treat them as such? You can spend all day soaking up the sun in your cutest one-piece, then throw on some high waisted jeans and heeled sandals or a midi skirt and sneakers before you head out to meet your BFFs for dinner. Unlike most other swimsuits, one-pieces are ridiculously versatile, and work both in the water and outside of it. Your summer wardrobe? Yeah, it just doubled in size.

Now that we all understand that one-piece swimsuits can be the base of multiple outfits, it’s time to stock up. Below, you’ll find 78 of the cutest plus-size one-piece swimsuits out there right now.
