i change my undies everyday because aren't you suppose to. as for my shirts and pants, i change them everyday but i don't wash it until i wear it 2 to 3 times then i wash it. after im done wearing it for the day, i would hang it up to let it dry out. then probably like a week later i would wear it again and then if i feel like it i put it in the dirty laundry if not ill hang it up again for another wear.
