Ha, ha, my boyfriend just made fun of me about this... But with my favorite clothes, if I didnt spill anything on it, and I didnt do some kind of aerobic work out in them then I put them back in the drawer to wear again. Whereas my boyfriend throws everything he wore that day into the wash. But seriously, you can go a week without cleaning your jeans, cant you?
I have to admit, if you look at various vacation pictures of me, I'm wearing several of the same shirts, from year to year, cuz those are my favorite clothes and I feel the most comfortable in them. Most noteably is a purple striped shirt that I've had since high school (!! which was almost 20 years ago!!). It appears on at least one day of every single vacation I've been on since 1993.
