Along with my current necklace problem (yes, I've been diagnosed); I also can't stop buying band t-shirts. Its probably my subconcious need to be like MK but nothing is more casually fashionable than throwing on a loose t-shirt paired with a huge necklace that makes it seem like your morning hangover couldn't stop you from making it to class in a cute outfit.
Necklace, Forever 21
T-shirt, Chaser LA (This brand is unbelievablely comfortable and has amazing designs!)
