We’re here to support you. When you need a little pick-me-up, you can always rely on the power of underwire. This kind of construction provides the lift, shape and support you need without ever sacrificing comfort. Trust us, when you put on one of our underwire swimsuits, you will look and feel your best! While anyone can wear underwire bathing suits, they are specially geared towards women with larger busts. We have these styles in all kinds of silhouettes like swimdresses and one pieces. So whether you prefer sexy underwire bikinis or chic tankini tops with underwire, we’ve got you covered. One of our most popular lines featuring underwire swimwear is GabiFresh x Swimsuits For All. This collection is available in cup sizes as large as G/H. Yes, that’s right. These suits are sexy, trendy and supportive! And did you know all our underwire styles fit just like your favorite bra? Go ahead, and choose your size in both our bra-sized and cup-sized swimwear. Our bra-sized styles come in sizes 36DD-46G, while our cup-sized suits are offered in sizes D/DD-G.H. To make shopping even simpler, we have matching icons so you can quickly find the underwire styles you’re looking for. Don’t wait any longer. Suit up in our styles, like an underwire tankini or bikini, and let your confidence shine!
