One Piece

One piece swimwear is the foundation of every great swim wardrobe. At Splash Swimwear, our carefully curated collection of women’s one piece swimsuits blends timeless design with modern fit technology, offering styles that feel supportive, flattering and effortless to wear.

From beach days and pool laps to resort holidays and weekend escapes, our one piece swimwear is designed to move with you — helping you feel confident, sculpted and comfortable wherever summer takes you.

Whether you’re looking for classic silhouettes, supportive designs or fashion-forward details, our one piece swimwear range offers options to suit different body shapes, bust sizes and personal style preferences.

Designed for Fit, Support & Confidence

Our one piece swimwear collection features a wide range of supportive and shaping designs, created to enhance the body without compromising on comfort. Many styles include clever features such as internal shelf bras, underwire support, adjustable straps, powermesh lining and contouring panels.

With options designed to suit a variety of bust needs — including larger cup sizes — one piece swimwear is a popular choice for women who want reliable support and a secure fit. If bust support is a priority, explore styles with underwire, higher necklines or wider straps for added lift and stability.

For women seeking extra length or coverage through the body, selected designs are also suitable for longer torsos, helping to prevent riding up and improve overall comfort.

Popular One Piece Swimwear Styles

Our one piece swimwear collection includes a diverse mix of classic and contemporary styles, so you can find the perfect fit for your needs:

Cross Front & Twist Front One Pieces

Cross front and twist front one piece swimsuits are loved for their flattering shape and bust-enhancing design. These styles often feature ruching or gathered detailing across the torso, helping to create a sculpted silhouette while offering support and coverage.

Cross Back One Pieces

Cross back one pieces combine elegant design with functional support. The crossed strap detail adds visual interest while providing extra security, making these styles ideal for swimming, beach walks or active days in the water.

Bandeau & Strapless One Pieces

Bandeau one piece swimwear offers a sleek, minimalist look and is perfect for sunbathing with fewer tan lines. Many strapless designs include removable straps, internal grip tape or structured support to help the swimsuit stay securely in place.

Longline & Full Coverage One Pieces

Longline one piece swimwear offers extended body coverage and a slightly lower leg line, creating a balanced and flattering shape. These styles are ideal for women who prefer a more modest fit without sacrificing style.

Colours, Prints & Seasonal Styles

From timeless classics to statement prints, our one piece swimwear collection offers a wide range of colours and designs to suit every taste.

Classic black one piece swimsuits remain a wardrobe essential, offering a sleek, slimming look that never dates. Neutral tones, soft pastels and ocean-inspired blues are perfect for understated summer styling, while bold prints, tropical florals and textured fabrics add personality and flair.

Whether you love minimalist designs or eye-catching patterns, there’s a one piece swimsuit to match your mood and destination.

Styling Your One Piece Beyond the Beach

One piece swimwear isn’t just for swimming — it’s one of the most versatile pieces in a summer wardrobe. Many one pieces double beautifully as bodysuits, making them easy to style beyond the water.

Pair your one piece with a sarong, linen pants or denim shorts for a relaxed resort look, or style it with a flowing skirt and sandals for beach-to-bar dressing. Lightweight and easy to pack, one piece swimwear is ideal for travel and holidays where versatility matters.
