  • Perfect coverage, stays put! Love this bathing suit top. The sizes do run smaller than what it says. I normally where a XL shirt and 38-40 DDD bra from Victoria Secrets but I had to go up to the plus size to get this to fit. Love it though!

  • Great support and style
  • It’s nearly impossible to find swimsuits with cup sizes larger than DD/DDD, even in plus-sizes; especially if you expect support in something you can wear all day that holds it all together, even when wet— but doesn’t look like your great-grandma’s “brassiere”! Elomi is my favorite brand, and this top is a great find. I have this one in both black and navy. NOTE: This style has an almost identical twin in the Elomi collection, but it has the word “Plunge” in its name. The only difference, from what I can tell, is the fabric between the cups—it’s maybe an inch or so higher-cut on this top. But that inch makes a BIG difference when you wear a large cup size!

  • Fits great
  • Have been looking for a tankini that fits both my top and doesnt highlight my fat near the hips or tummy. One caveat is the underwire provided is not that supportive. You may need to buy a swimming bra in addition to the suit.

Plus Size Underwire Swimsuits

We could all use a little extra support sometimes. That’s where plus size underwire swimsuits come into play. Not only are they super for support, plus size bathing suits with underwire lift and shape, too, meaning these swimsuits actually look more figure-flattering than their stringy counterparts.


There are no style restrictions, either. You can rock a strappy one-piece or a bold bikini and still have the structure you need to look and feel your best for a day at the beach. So pick a color, any color, from understated navy to electric neon, and suit up without fearing a lack of support. With swimwear underwire swimsuits made by your favorite bra brands, your beach body gets the very best.
