A puddle's worst nightmare. A thick moisture-wicking sock built into tights, grab yourself some Boottights ($30) before all of the Oprah fiends get to them! (Oprah says these revolutionized her life, much like Spanx.)
Like having a corset waist built into your puffy coat, this Eddie Bauer Slope Slide Down parka slims every size--and it's available from extra small to 3X ($178).
A scarf that turns into a blanket, and feels like a t-shirt = amazing. Get this Nomad by Fluxus scarf ($50).
