a lot of people actually wear the hoodie both inside and out of uni. i live fairly close to campus, and just walking around the area (like to the vic market/mc/etc) i always notice a fair few people wearing it.
i don't own one myself though, if i wanted to wear a hoodie, i'd still wear my year 12 one. XP #noshame
If you want the girls, you will need to be rocking a $2000 suit with a $25k Patek Philippe Calatrava 5107 timepiece. Don't forget the luxury BMW in the carpark. Forget backpacks, you need a high end LV briefcase.
jks of course, the hoodie is fine 
LOL. some guy on campus actually tried to pick me up by being like "oh you do accelerated math, i'm a physicist. and i have a bmw, wanna come out for a ride?" i had so much trouble not laughing in his face.
