Well, my 'wardrobe' isn't so big. I have a lot of clothes in my bureau, yes, but less than half of them are mine/actually fit me. (and some of it is winter clothes)
The clothes I really wear are pilled up in the corner of my bed, I think I have around 5 or 6 pairs of pants and 9 or 10 shirts that I actually wear.
As for shopping, the only things I buy but don't wear are things I don't want to buy. Like my aunts made me get this wierd dress, but I have no intention of wearing it. :P
