Bought these for myself for Christmas, I wear a XL comfortably but it will be form fitting against my body. Some of the things I wear, I like to be a much bigger size especially when I sleep because of my fibromyalgia, it's just more comfortable to wear looser clothing.
I bought this set in a 2XL.
It fits like a XL, normally a 2XL is pretty baggy on me. This set is not, this 2XL is very form fitting. I hated the feel of the pajamas as well, while the outside is silky and soft the inside is not.
The inside is the kind of fabric that will sang on a hangnail or a piece of dry skin, not even exaggerating, my hands were dryer then normal and had I had a dry hangnail piece of skin that kept on snagging on the inside of the pajama shirt as I was trying it on and taking it off.
Now I want to say that I can't wear certain materials because I have super sensitive skin and the inside of the shirt is definitely one of those materials. But other people might be just fine with how this set feels and wears but not me.
Based on just my experience with the set, I would not recommend these pajamas to family or friend's, mostly because I know their taste and dislikes. However other's might find this set nice.
It's just not my cup of tea. ☕
