I wear black skinny jeans 6 days of the week. Currently wearing the primark super highwaisted ones. I have noticed they fade after 3 washes mostly around the edges. Im buying a new pair every few weeks, because they fade and because im trying to shift a few extra lbs. Can anyone suggest any that dont fade so quick? I dont have a huge budget and would need 2 pairs atleast. I usually have them on from 7am to about 8pm. Thanks in advance.
