Spotted in NYC on Tuesday (and participating in a habit we don't condone), the designer wore a red zip-up hoodie, black structured pants, black sandals, and round sunglasses, and completed her outfit with a cardigan around her waist. However, it was the way she wore the piece that made us do a double-take. Rather than knotting the sleeves like one would expect, Olsen slipped her body through the neck hole and buttoned up the bottom to keep it in place.

Olsen didn't even need statement pants, to be honest; her sweater acted just like a skirt, and without the slacks, she'd have yet another interesting look.
