Good quality, comfortable, go nice and high on the waist. I'm 170cm approximately. Would be very tight if more than UK/IRL size 10 though I'd say. For One Size that's not a wide spectrum! If you like to use leggings as trousers these look funny with the seams, sort of like hosiery! A long top or dress essential. Very nice comfortable product though and good choice of colours.
They are a little bit transparent, so if you dont want to share your panties, you better wear a dress or long shirt with them. On the other hand, they are very comfortable, nice cashmere inside. For the M size, they might be too tight on belly.
