WALMART! if you're from canada.. If not, steer away from it. If I remember correctly, there's places like marshalls and winners that sell legit products for much much less. That's if you're worried about quality. If not, target's good
What i do is i will goto a used clothing store ( Value Village ) and look at the jeans. Look for ones the will fit you great in the upper half of the jean. Then i buy then for approx 7$ each and bring them home and make my own shorts. I find they look better than any of my other shorts iv payed big bucks for. You can look up youtube tutorials how to make shorts out of jeans! I personally usually always get american eagle jeans, which are pricy (50$) and make shorts out of them for 7$!
