My wardrobe sucks. Just about every day I wear an old t-shirt and an old pair of jeans, with converse shoes that are falling apart. I need grown-up clothes, but I have no clue where to shop, what to look for, etc. This summer I decided to give myself a ~makeover~ which basically means getting a nice haircut and buying nicer clothes. What should I buy? I live in Southern CA if that makes any difference.
ETA: Pictures would also help :D
What is your favorite item of clothing?
