Ordered a size 8 when I'm usually a size 8 and they fit perfectly. They are a thin material and a little see thru but other than that I love them. Only thing is you need to put your own sole in for more comfort. I ordered black ones too and they were perfect.
I love these! They fit perfectly! Keep in mind they are slightly sheer. But overall I think they are so cute. Not sure if they are real, It came from China for me. Also is very comfortable & lightweight.
