Don't trust the website reviews
My initial review of their products was a 3 star but on finding out they remove reviews from their site, falsely representing items has reduced this.
The material used is thick and breathable but micro modal isn't as eco as advertised as uses harsh chemicals to break down the wood fibre then to bond it again.
The fitting was a problem, I sized up as I was in-between as recommended but the leggings were extremely long yet the onesie short in the leg for the same size. The onesie body is also very short ( I'm 5'4'')
I found the inner thigh seams start to bobble very quickly and really offers considerable camel toe.
I wonder if they have only been designed for very thin people as the models are. (I'm a UK 14/16) Maybe their legs don't touch and their waistband doesn't move downwards constantly.
I have POTs and didn't see any benefit to wearing these in all honesty.
I wish I had done more research before splashing out.
