So these leggings (in my case, dark gray and light gray size M) is just great! Goods came in vorraussichtlichen delivery on the first day. I was very surprised because my mother went out and came back with a package and she thought it would be for my stepfather. Anyway, I've been wondering about the interface because my other leggings look different. But I've tried both the same and fit perfectly. I would definitely recommend. I am very pleased!
