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.

    Great Fit!

    I just received this suit & its FABULOUS!!! I haven't had a new bathing suit in forever, but we're going to Hawaii & Mexico soon so I thought it was time. This suit fits great and is flattering. Its made very well and Im sure I'll have it for many years to come. A big plus, my husband loved it!!! I also found a coupon, so didn't pay full price :D

    Super sexy

    This swimsuit is super sexy! Only problem I have is that the boob part is not supportive enough. I wear a torrid 38DDD or a lane bryant 40 F in bras. The underwire is nice but theres not enough support or space to fit my whole breast to it sort of sticks out past the underwire. Otherwise this is a perfect suit!

    Adorable Retro Suit!

    This swimsuit looks so great on. It's very flattering and I feel like I have a true hourglass figure. My only recommendation is to order up 2 sizes at least! I originally ordered in a 14 (I usually order size 12 bottoms and size 14 tops from this site), and I had to return for a size 18!!! I'm a 38DD, 5 feet tall, and usually wear a size 12-14 in jeans and dresses. Considering how annoying it is to return things through this site, I thought I'd warn you to go up a size if you want the perfect fit! You won't be disappointed once you put it on...I can't wait to wear for my cruise this week!
