Sexy Swimming Costumes for Summer: Make a Splash in the Season’s Hottest Swimwear
Looking for a one-piece that turns heads and makes you feel amazing? This Summer, sexy swimming costumes are all about confident cuts, sculpting support and playful design details. Whether you're planning a beach holiday, lounging poolside, or heading to a rooftop party, a stylish one-piece is your swimwear power move. Below, we’ve rounded up what makes a swimsuit seriously sexy - plus a few of Boux Avenue’s most flattering styles for every shape.
Why One-Piece Swimsuits Are Hotter Than Ever
Today’s one-piece swimsuits prove that full coverage can still feel daring, with clever design features that do the most. Think high-leg silhouettes, deep plunges, curve-contouring seams, and luxe textures that catch the light.
Modern one-pieces are equal parts fashion and function. They offer extra support, flatter your shape, and come in bold, look-at-me designs that bring serious confidence. Whether you want a classic bombshell vibe or an edgy, cut-out look, the right swimsuit does it all.
What Makes a Swimsuit Seriously Sexy?
Think sexy means skimpy? Think again. The hottest one-piece swimsuits prove that less isn’t always more. Here’s what to keep in mind when you’re swimsuit shopping this Summer - with a few flirty features to add to your wishlist:
If you’re feeling daring, try a style with strategic cut-outs. A flash of skin at the waist or under the bust adds just the right amount of drama, without compromising on comfort.
Looking to flatter your curves? Say yes to ruching. It smooths, shapes, and defines - especially around the waist - giving you that extra dose of confidence by the pool.
If you’re drawn to bold finishes, metallics and chic monochrome styles always bring the glam. Think sunset selfies and cocktail-hour sparkle.
High-leg cuts are made for that legs-for-days look - elongating your silhouette in an instant. And if you're after all-day support? Seek out swimsuits with firm, stretchy fabric that holds everything in place, while still feeling soft against your skin.
So, which sexy detail is calling your name? Let’s find the one-piece that makes you feel your best…
The Best Sexy One-Piece Swimsuits for Women
(Including Curvy Picks)
Valentina Ruched Super Push-Up Swimsuit
For bombshell energy, look no further. The Valentina Swimsuit combines luxe ruching, a super push-up fit and a flattering plunge – perfect for enhancing your natural shape, and available in sizes up to a DD. Ideal for pool parties or glam holiday pics.
Ibiza Ombre Cut-Out Swimsuit
The Ibiza Swimsuit is all about bold, body-loving design. The ombre effect turns heads, while front and side cut-outs create an hourglass illusion. Plus, it’s got a high-leg silhouette to elongate your frame.
Amalfi Crinkle Swimsuit
Curvy girls, meet your new go-to. The Amalfi Crinkle Swimsuit’s textured fabric sculpts without squeezing, and the balconette cups offer secure support. A perfect pick for anyone searching for sexy bathing suits for curvy women that feel as good as they look.
Style It Up - One-Piece, Endless Looks
A sexy one-piece isn’t just for the beach - it’s the ultimate Summer wardrobe staple that can take you from sand to streets with ease. Whether you’re poolside, at brunch, or heading out for a night of fun, your one-piece can do it all. For a beach vibe, slip on a sheer maxi or sarong over your swimsuit, throw on some gold hoops, and grab a cocktail. You’re ready to make an entrance. When the sun sets, transform your one-piece into an evening ensemble by pairing it with wide-leg linen trousers and a pair of wedges - perfect for dinner by the sea or a sunset stroll. Heading to a festival or a city break? Style your swimsuit as a bodysuit, tucking it into denim shorts and layering with a kimono for that easy, bohemian look. Your one-piece is more than just swimwear - it's a versatile piece that can handle every part of your Summer plans. The secret to a stylish Summer? It’s all in the one-piece.
Boux Knows: How to Find Your Most Flattering Fit
Not sure which swimsuit suits you best? Start with shape-enhancing features that will flatter and celebrate your unique shape.
If you have a smaller bust, look for swimsuits with structured designs that provide natural lift and shape, or experiment with a fuller silhouette using some of our double padded designs. Styles with v-necklines or plunge cuts can also enhance your silhouette, adding the illusion of more volume while keeping things comfortable and flattering.
For those with a fuller bust, opt for swimsuits with wider straps, structured cups, and underband support. These features provide added support, ensuring you feel secure and confident, whether you're lounging by the pool or catching some waves.
If you’ve got a curvy shape, try cut-outs, ruching, crinkle fabric or wrap styles. These clever design details help define your waist and enhance your curves, creating a balanced and flattering silhouette that works with your natural shape. It’s all about accentuating what you love most about your body, while looking luxurious.
