These are just the softest thing i have ever worn to sleep in.  i wear like a size 16 in tops and 20 in pants so i actually ordered the XL and the 1X and they both fit me.  The 1x is more of a wider or more baggy fit, which i kind of like.
At first i washed them on delicate but next time i washed them in heavy duty hot water wash with the other pyjamas and sheets and things... They didn't shrink noticeably.
I don't know what else to say about them, they are pretty much just amazing pyjamas.
