Reviews

I am a big fan

"I am a big fan of Une Piece togs, and this one shoulder is a lovely style, but needs more support in the tummy region"

Michele M. (4/5)

Quality is premium, waist area

"Quality is premium, waist area is great, style doesn’t suit me unfortunately. Downside of having no stores. Probably won’t risk online again. 181cm tall meant had to exchange for bigger size."

Hi I’m so upset, I

"Hi I’m so upset, I purchased this over the holiday period and unfortunately the bathers are too big. I was on holidays and unable to return or exchange it for another size. The 7 day returns window is unreasonable given how expensive the product is."
