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 (2-20). Ensuring the right amount of fabric, coverage and superior bust support for a confident, beautifully considered fit.

Reviews

Beautiful colour comfy and nice

"Beautiful colour comfy and nice bum cover ! Love the texture ."

— Bid A. (5/5)

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)

Didn’t fit right. Crinkle fabric

"Didn’t fit right. Crinkle fabric too thick and don’t offer a refund."

— Carla H. (1/5)

Fits Beautifully. Gorgeous.

Bad customer service - return not allowed

"This suit is ok. The material is nice. The cut is not super flattering. Return limit is 14 days including getting it back to them. This is terrible customer service given the price point. The website says you can get store credit after 14 days. I wanted to exchange the green suit I ordered for a smaller black one, but when I entered my order number it said it was unavailable. I am at like 20 days. It is not like it has been way too long. I would not order from this company again and would not advise anyone else to."

— Mary C. (2/5)

Great fit although haven’t worn

"Great fit although haven’t worn them in the water yet. Hopefully no sagging."
