Shirt (Dress?): Aerie
Belt: ASOS (out of stock)
Pants: Gap Link!
Boots: Nine West Outlet
I wore this last week on a day when it was freeeeeezing outside! I just had that "I want to be warm" feeling, so I pulled out this long sweatshirt type thing and at first I said to myself that it was too casual for work. Then I put on the bow belt and voila! a little more work appropriate (although there's no disguising that it's a sweatshirt, I realize that ;)).
Unfortunately, this belt is sold out on ASOS but if you just search for "bow belt" that have a lot of others to choose from!
