How to Choose the Perfect One Piece Swimsuit
With 94 styles to explore at Oh So Luxe, here's how to find your ideal match:
- Want tummy control? Look for styles with built-in smoothing panels — Madora's tummy-control one piece and Marko's tummy-masking strap monokini are two of our most-loved styles for a reason. They shape beautifully without feeling restrictive.
- After a push-up effect? Several styles in our collection feature structured padded cups that lift and enhance naturally. Lupo Line's push-up one piece and Marko's Cuban-style monokini are standout options.
- Love a bold look? Our cut-out, plunge and Brazilian-back styles — including the YesX deep plunge and Marko's ethno patterned cut-out — are perfect if you want your swimsuit to make a statement.
- Prefer classic coverage? A streamlined swimming costume in a solid colour or elegant print gives a polished, timeless look that works beautifully for pool sessions and beach holidays alike.
- Need sizing advice? Sizing varies across brands in this collection. The Oh So Luxe team is always happy to help — just get in touch before you order and we'll point you in the right direction.
Swimsuit Care & Storage Tips
Keep your one piece swimsuits looking and feeling their best all season long:
- Rinse after every wear — cool, clean water removes chlorine and salt that degrade elastane fibres and fade prints over time.
- Hand wash gently — use a mild detergent in cool water. Machine washing can distort padded cups, stretch fabric and damage decorative details like brooches or gold accents.
- Never wring or tumble dry — gently press out excess water and lay flat to dry in the shade. Direct sunlight weakens fabric and fades bold prints.
- Store flat or rolled — avoid folding on cups or embellishments. Store in a breathable bag or flat in a drawer between wears to maintain shape.
- Rotate your swimwear — if you swim regularly, alternating between two pieces gives the fabric time to recover its elasticity between wears.
Frequently Asked Questions
Do you stock tummy control swimsuits?
Yes — several styles in our one piece collection feature built-in tummy control panels that smooth and shape beautifully without feeling restrictive. If you'd like specific recommendations on the best tummy control styles currently in stock, the Oh So Luxe team is always happy to help — just get in touch.
What's the difference between a one piece swimsuit and a monokini?
A one piece swimsuit provides full front coverage, while a monokini features cut-outs — typically at the sides or waist — for a bolder, more fashion-forward look. Both styles are available in our collection, from classic swimming costumes to Brazilian-back monokinis with brooch accents.
Do you stock one piece swimsuits for larger busts?
Yes — we stock several styles with underwired cups, wide straps and structured support specifically designed for larger busts. Lupo Line's push-up one piece for larger busts is a particular favourite. If you'd like personalised recommendations, the Oh So Luxe team is always happy to help.
