These are the most gorgeous pajamas I have ever owned, they're SO soft to the touch and feel absoloutely beautiful on. Sleeping in them, I felt like my temperature was being auto-adjusted because of them. Definitely buy them if youre debating!!
All this said, Im a UK 10 on top and UK 10-12 on bottoms. Unfortunately clothes (everywhere) dont seem to be made for size 10-12 anymore! My options for the pajamas were either 8-10 or 12-14 so I got the 12-14 as I have wider hips and it was the size recommended to me.
The result is that the top is quite large (but not revealing) while the trousers fit me just enough that they wont drop to the floor or slip off in the middle of the night but are so long. I wont be swappjng for the 8-10 though as Im worried they will be too tight! So, an in-between size or as others have said, being able to buy tops and bottoms separately in the future would be great!
