One Piece Swimwear - Page 14

One piece swimsuits form the foundation of any holiday wardrobe. Our signature collection of styles combine athletic lines with innovative panelling and contemporary details to leave you feeling sculpted, supported and confident. 

Designed in Australia since 2018, we believe in enhancing a woman’s body, using the most innovative technology to create a wide selection of flattering and sculpting designs – our essential one piece swimwear is timeless and made from the highest quality fabrics, combining elegant lines with clever contemporary details to match any mood.

Our curated collection of one-piece swimwear proudly offers an extensive range of fit and cup size options, from A to G cup fits and inclusive sizing from AUS/UK 8 to 20 (i.e. US 4 to 16 & FR 36 to 48). 

One Piece Swimwear & Eco-Friendly Fabrics 

Our one piece swimsuits are made from advanced eco-friendly fabrics which use regenerated nylon yarns derived from pre-consumer waste. We use advanced technology so not only do these recycled textiles maintain a durable soft feel and premium quality, they also provide UPF 50+ sun protection. 

Our Favourite One Piece Swimwear Styles 

Our one piece swimwear also utilises precision contouring and is available in a full offering of sizes, each style is expertly designed to enhance the body with ultimate support and comfort. Here, you can select from some of our most popular one piece styles, to find the one that complements your style and preference.  

Cross Front One Pieces

 Our cross front one pieces, twist front one pieces and panel line one pieces are must-have styles that incorporate sculpting technology via powermesh panelling at the front and back of the body, and all are available in a full range of cup sizes including D and DD cups.

Cross Back One Pieces

For a flattering silhouette that is as timeless as it is elegant, our cross-back one piece swimwear is another swim staple for this season. While the low back design creates a classic look, the supportive cross-back straps offer added security and comfort. From our cross-back triangle one pieces to our cross-back halter neck one pieces, this style belongs in every woman's swim collection. 

Longline One Pieces 

Longline one piece swimwear offers a twist on the classic one piece. With an elongated torso and extended body coverage, our longline one piece swimwear is designed to be flattering on all body types. Unlike our classic one pieces that sit higher on the hip, our longline one piece swimwear features a lower leg cut and more defined waistline.  

Bandeau One Pieces 

Our bandeau one piece swimwear and halter bandeau one piece swimwear features a strapless neckline that highlights the shoulders and collarbones. They offer a more minimalist look, making them perfect for sunbathing with no tan lines. Whether you are lounging poolside or styling it with a wide-leg pant for a beach-to-bar moment, the bandeau one piece is a timeless choice.  

Discover Our One Piece Swimwear Colours & Prints 

From timeless monochromes like our black one piece swimsuits to our eye-catching prints, we offer an extensive colour palette. Classic black one pieces offer a slimming look that will never go out of style. Soft pastels and seasonal shades such as ocean blue, navy or red brings a gentle, beachy vibe for summers spent by the pool. If you want to stand out at the beach, we have tropical florals, retro stripes, scalloped one pieces, scoop neck one pieces, animal prints and abstract designs. Whether you find yourself drawn to minimalist designs or love making a statement, we have something for everyone. 

Styling Your One Piece Swimwear

Styling one piece swimwear goes beyond the beach, our one pieces transition from swim to street. For a post-swim look, throw on a linen button-up shirt and high-waisted shorts or a stylish sarong. Our one piece swimwear also looks great styled with a flowing maxi skirt and strappy sandals when visiting coastal destinations. One pieces are a great foundation for a range of outfits and the best part is they don’t take up much room in your suitcase at all!

Women’s One Piece Swimwear FAQs 

Can I wear a one piece as a bodysuit? 

Yes! Our one pieces double up as bodysuits and can be layered under flowy pants or maxi skirts on holidays, which is a great way to save space in your suitcase when travelling. Heading straight to the lunch after the beach? Throw a skirt over your one piece and you’re ready to go.  

Do one pieces offer enough support for a larger bust?  

With features like underwire, built-in cups, adjustable straps and higher necklines for added support, our one piece range has a wide selection of swimsuits suitable for larger bust sizes. If you are looking to shop swimsuits with a larger cup size exclusively, shop our swimwear ranges by cup size like our D Cup swimwear and E Cup swimwear collections.  

Are one piece swimsuits flattering for all body types? 

At Sea Level Australia, our one pieces come in a wide range of cuts and styles, from high-leg styles and plunging necklines to longline silhouettes. Highlight your curves, add support or achieve a sleek shape at the beach or the by pool with our one piece bathers collection.
