I actually do need stuff for uni.
I'm going back as "permanently dolled up and vintage December" not "I couldn't be bothered today so I will just throw on these jeans and a band t-shirt December".
So I need to get a whole wardrobe of vintagey clothes (authentic or otherwise) so that I have enough to do it day in day out. And I am only going to take those clothes so I can't be tempted to throw on a pair of jeans if I'm feeling lazy.
My wardrobe is expanding pretty well actually. Primark is the best! H&M has some nice stuff too- I bought two lovely puffy 50s style skirts in there the other day: one polka dot and one flowery. They're gorgeous and the flowery one was £5 in the sale
Ok, so maybe I don't "need" stuff...
