Buy Definition currently has a sweet deal, where all its tops, including sweaters, pullovers, tees, and blouses, are 20 percent off. I'm thinking this Kai-aakmann Hooded Oversized Poncho ($94, originally $118) would keep me warm and on trend. Other styles include sequins, ruffles, draping, prints, and shredding. See for yourself, and be sure to enter CODETOP20 upon checkout. Offer expires Saturday, Oct. 31 (Halloween!), so hurry.
