Blouse, Club Monaco. Sweater, Banana Republic. Skirt, Brooks Brothers. Pumps, Nine West.
Not a costume per se, but costumey enough. I found this silk blouse in a thrift store in perfect condition because really, where would one wear such a collar? I call it Marcella Marceau or Class Clown, which is odd since I'm a teacher. Now - who wants a balloon animal? I can make hyphens, commas, and parentheses. Yes, that kind of teacher.
