There isn't much fading. The elastic waistband is quite firm, so they stayed in place without slipping. Adidas pants usually slip down unless you tie the drawstring. These don't slip at all. But they're not too tight either... There's a part of the seat that's a darker color. Please check the photos! They're very cute. I was able to wear them until size 90! I will cut off the tag because it has my name on it before shipping. Thank you.
