Here's another look, now that I'm trying to take my blog more seriously:
Sweater: Forever 21
Boots: Urban Outfitters
Jeans: somewhere in Uruguay
I really don't think you have to have tons of clothes... you just have to match them differently. And if there's something you really like, you need time to wear it over and over. Right now, as you can see, I've been wearing these boots a lot, even if I have other boots in my closet!
