At UB, you need to wear business casual with a white lab coat or scrubs (any color, any style) anytime you're in clinic, preclin, or any sort of lab (gross, histo, etc.) In lecture you can wear whatever you want...girls can get as skanked out as they want and guys can look like hobos. Both of which happens 😀 Second semester first year we get to wear real clothes 4 days out of the week! yay for not ironing!
Oh, and if you're in the lab coat/scrubs thing you also can't wear hats of any kind, sneakers, etc. But you can buy whatever scrubs you want and most people do that rather than dress nicely AND wear an ironed lab coat.
