Hmmm...not only do most TFPers have dirty minds, most of them also wear dirty clothes
.
Assuming that I wear the article of clothing all day:
Shirts--Unless I wore a t-shirt under it, usually get washed after one wearing (Houston humidity). I
might go two wearings if I did nothing but sit around the air-conditioned house, or I plan to wear it for yardwork.
Jeans--Two wearings because they relax & get too baggy. I might go three wearings, but only if the third involves yardwork or something similar.
Dress pants--Three to four wearings, unless I get them dirty. It also depends on the color & the fabric.
Underwear & socks--Everyday, except maybe if I going to do yardwork or something similar.
