i am a female. and tend to do the same thing. i get lazy and rarely hang up my clothes. i only do so if im on vacation and have time. other than that my close just lies in the laundry basket. it's doesnt really get wrinkled. i mean, it's jeans... and t-shirts. nothing special.
so no, i don't feel weird when wearing wrinkled clothes.
