You will have plenty of time to worry about clothes when you have income later on.
You can get girls for free. You can also get decent underwear on the cheap. Condoms are free at most universities. You shouldn't smoke weed. Lastly, good clothes will help you get girls, and will give you pleasure for far longer than a girl you meet at a party will.
To answer the original question, it really depends. If you have something you really want and are of a normal size s/m, you should probably get it either now or next cut. If you are eyeing an 'out there' piece, or wear l/xl/xxl, then wait till the final cut.
