Although these are very cool to look at they are quite low rise and the tights material on the inside ripped on first wear adds to the look so not too bothered. I wear a UK size 14-16 and ordered XXL and they just fit on the tummy.
These are like a double-thickness "Tights" sort of fabric, therefore opaque,in nature. Very comfy, to wear and a very versatile piece to have
Brought a size XXL I would need to size up atleast 2 more sizes for them too fit. So if your a 16/18 do not order an XXL.
