It's hard to have fun when you're worried about how you look! swimsuitsforall was founded on the belief that all women deserve to fully enjoy occasions that call for wearing swimsuits. That's why we've put together an unbeatable selection of plus size swimwear designs in sizes 8 to 34. With fit solutions for women of all shapes, our collection of bikinis, tankinis and one piece swimwear designs offers something for everyone, including a wide variety of underwire swimsuits.

If you've been blessed with a big bust, finding one piece swimwear fashions with a proper fit can be tricky. Large breasts require plus size swimwear with extra support to ensure comfort and prevent sagging. Underwire swimwear is designed specifically to provide the support that you require to look and feel your best whether you're swimming for exercise, soaking in the sun on the sand or mingling at a pool party.

Underwire one piece swimwear styles provide full coverage for the torso just like conventional one piece swimwear, but they have a special added feature that makes them unique. In the cup area, the underwire swimwear features metal wires that are bent in the shape of a "U." The wires in the one piece swimwear rest directly beneath your breasts and lift them from the bottom. As a result, underwire swimsuits offer support that is similar to what you're accustomed to when wearing a bra. We carefully select the plus size swimwear designs with underwire that we carry to ensure that the wires are well made, so you won't have to worry about painful rubbing or poking when you choose one of the swimsuits from our collection.

At swimsuitsforall, you'll find underwire swimsuits in a wide array of silhouettes and styles, so there is certain to be a one piece swimwear look that you'll love in our collection. If you're not sure how to begin shopping for underwire swimwear, there's no need to stress! Our plus size swimwear experts are here to make things easy. One of our knowledgeable customer service representatives will be glad to discuss your needs and preferences with you and recommend underwire one piece swimwear designs that are the best choice for you. Our experts can even give you advice on how to match your favorite swimsuits with cover ups cover ups to create full ensembles for the beach or pool.

    Sexy without exposing problem areas. Great design.

    Gabifresh does it again!

    This swimsuit is great! The mesh side panels aren't too revealing and the high waist bottom is great for covering the ares I don't want to show. The bra top fits very well and has plenty of room for me and has good support. The back closure is my only issue, in that it always slips crooked. I usually remedy this by taking a small piece of double-sided tape and wrapping it around the hook. It works well enough and doesn't get gummed up. I'll be a loyal customer!

    I love the suit BUT...

    according to measurements I needed a 22 but it's too big and it's not in stock for me to reorder. The overall exchange policy is a bit cumbersome considering I can't wear what I have and can't reorder another. I don't want a different suit...

  5. 4 out of 5 stars.

    Sexy, stylish & fierce.... but not too supportive.

    I purchased this swimsuit a few weeks ago, very stylish very sexy but not really supportive in the breast area especially for women with heavier, fuller breasts. I'm a size 14, purchased a 14, suit fits fine in the torso area even had some room to play with but when it comes to the breasts area I was a lil' bit upset. The halter ties could have been a tad bit wider, the thin ties dug into my neck as I had to tie them really tight to get some support. I felt like the underwire could have been sturdier for us women who are heavier up top. I'm a size 36jj up top, 5'4 with an athletic frame.
