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.

    So chic

    I adore this swimsuit. I bought it for vacation and it just looks right in every way. I purchased a size 16 E/F and it fits perfectly. I also purchased the matching coverup and the colors look great together! Best collab to happen on swimsuitsforall

    Great suit

    Well made and flattering style. I am 6'1" so it was too short. Disappointed.

    I loooove this swimsuit

    I just received this swimsuit today and for the first time ever I had a happy surprise when I put it on. The pattern and style are very flattering and it fits perfectly.

    Cutouts in all the right places!

    I've had a baby so my stomach isn't what it used to be. I already have a high waisted bikini so I was looking for something different. I couldn't be happier with this one. It fits perfectly and it accentuates all the right places while hiding what I need it to.

  5. 3 out of 5 stars.

    Beautiful but the clasp sucks

    I love love this. I got it for a baecation that I'm planning. However I sized up, because I'm too heavy and the cups fit perfectly but the clasp in the back is the real issue. It's extremely hard to close by myself. I would definitely need help closing it. That's the only negative thing. I'll keep it because I love it but next time maybe something a little easier to get into would be ideal.
