I don't usually do this at school because I don't want people to think I'm unhygienic but I can totally understand if you blow $50 dollars on an expensive outfit and want to wear it twice. I think others will understand too. I recommend wearing it for only 4-6 hours one day and then wearing the same outfit for another 4-6 hours the next day. It's okay to wear the same outfit 2 days in a row if you don't wear it the entire day. Keep it for a party, change clothes when you get home, and then when you go to a party again put it back on.
