Instead of relying on extra padding or other support mechanisms, underwire swimsuits use cups lined with plastic or metal wire, which means lifted, supported boobs for you. Goodbye, annoying pads that get all folded up inside your swimsuit top!How to choose the best underwire swimsuitJust like when you're shopping for any type of bra, you want to think about how much support you'll need and what kind of activities you'll be doing ('cause a nip slip is a great way to spoil a day, ya know??). A few things to keep in mind as you shop:Consider the style Underwire bathing suits come in tons of different coverage styles, and the one you pick all depending on your bust size and comfort level. Those who don't wanna risk any spillage should probably choose a full coverage top, while those who like moderate coverage should opt for a demi-cup suit. And if you really wanna showcase some cleavage, then a balconette or plunge swimsuit is the way go.Check out the strapsLike underwire, straps are key when it comes to support, and typically, a thicker strap means more stability and less movement (not to mention that thinner straps are far more likely to dig into your shoulders or neck). If you have a bigger bust, you probably also want to look for straps that are wide, adjustable, and—ideally—convertible, so you can customize your fit and make sure they stay firmly in place.Find the right fitShopping for swimwear online can be tricky, especially when it comes to underwire suits. While browsing, consider whether you'd like a compressive or more relaxed fit, then read reviews to see if you should size up, down, or go with your regular bra size. The best swim tops and one-pieces tend to be those that are fully adjustable so you can customize your fit as needed (which is especially important if you're someone with a larger bust and smaller ribcage).Advertisement - Continue Reading BelowWhy trust 'Cosmo'?Cosmo's team of digital fashion experts has decades of combined experience in the industry.
