Fabulous slim fit denim stretch girlfriend jeans. The label on them says boyfriend but I think they are more girlfriend. These are relaxed at the waist, with a small pleat each side of the zip. The leg is slim leg with a nice fit. They are VERY comfy.
70% cotton 28% polyester 2% elastane
The waistband is very stretchy, and the fully stretched measurement fits each size nicely. See guide below. For instance I am a size 10 and wear a 28" waist on my jeans. Once on and done up, with the waistband stretched to 28" the S size fits me perfectly. The next size up was too big on me.
XS - UK8 (Waist measures 24" unstretched, and 27" stretched)
