Goody two-shoes

I never understood the whole "goody two-shoes" term. Who came up with it? Why is wearing two shoes bad? Anywho- well I named this post for the fact that my outfit is a little out of my ordinary black and combat boots zone. I have my new Ann Taylor skirt from Scout, a new Gap top that I bought in my grab bag at Plato's closet, and a new necklace that Alex bought for me. I'm rather a big fan of this outfit, I'd say. :)
