How would I style a crinkle swimsuit?

Our Crinkle swimsuit is easy to style for beach days, resortwear, and holidays. Wear it on its own, or pair it with a beach sarong, wide brim sun hat, or relaxed cover up for an effortless beach-to-bar look.

How does the adjustable leg height work on the Crinkle one piece swimsuit?

The adjustable leg height lets you customise how the Crinkle one piece swimsuit sits on your hips. You can wear the leg line higher for a more elongated look, or lower for more coverage and comfort. Combined with the soft, stretchy Crinkle fabric, this helps you adjust the fit to suit your preferred shape, coverage, and feel.

Is the Crinkle one piece good for a long torso?

Yes. Our Crinkle Cut Swimsuit can be a great option for longer torsos, thanks to its soft, stretchy Crinkle fabric and fully adjustable leg height. You can wear the leg higher or lower on the hip to customise the fit, coverage, and feel on your body.

Does the Crinkle one piece have tummy control?

Our Crinkle Cut Swimsuit offers a supportive and flattering fit, but it does not provide the same firm tummy control as our Core fabric. Our Crinkle fabric is softer, stretchier, and more textured, giving it a comfortable and flexible feel on the body.

What is crinkle fabric and how is it different from regular swimwear fabric?

Our Crinkle swimwear fabric has a textured, stretchy feel that gives our swimsuits a soft, flexible fit with a unique crinkle finish. Compared to our Classic swimwear fabric, Crinkle feels stretchier and more flexible, while Classic feels smoother, firmer, and more sculpting on the body.

Our first model wears size AU 8 (US 4). She is 176cm (5'9") tall with an 85cm (33") bust, a 61cm (24") waist and 90cm (35") hips. Our second model wears size AU 8. She is 173cm (5'8") tall with an 81cm (32") bust, a 64cm (25") waist and 89cm (35") hips.

Most crinkle swim is made to be “one size fits all” - but we don’t believe one size can truly support and flatter every body size and shape.

After doing fittings with over 50 women (of different ages and sizes) from our UNE PIECE community, we chose to craft our Crinkle Cut Swim in individual sizes (6-24). Ensuring the right amount of fabric, coverage and superior bust support for a confident, beautifully considered fit.

How to measure

Bust: Using a flexible tape measure, measure across the fullest part of your chest, ensuring the tape measure is straight across your back.
Underbust: Measure directly under your bust, where the band of a bra would sit.
Waist: Measure around your natural waistline — this is the narrowest part of your torso, usually right above your belly button.
Hips: Stand with your heels together and measure around the fullest part of your hips and bottom.

Gorgeous Crinkle One piece. Une

Very comfortable. My only issue

"Very comfortable. My only issue is the shelf bra section is quite small for my DD size bust. Size 16 should be a little more generous in this area."

Adore these swimsuits and the

"Adore these swimsuits and the crinkle cut fabric. They have the same look as another brand but with more support which I love. The only downside is that the fabric easily picks/snags after just one wear. I purchased during pregnancy and the coverage is great without having to size up too much. I can never wear one pieces because I have a long torso but this one is very comfortable!"

— Emily W. (4/5)

Very pleased

"Very pleased with this suit. Fabric is a nice quality and mid-weight. Keeps everything in without feeling too tight. Fit is flattering and coverage is good. 5' 6", 130 lbs and I ordered a size 6. Already considering what color to order next!"

— Christina H. (5/5)

Fits Beautifully. Gorgeous.
