Seriously cropped and seriously sexy, shrunken tie-front sweaters should be on the must-have list for anyone who is anyone. Usually worn over longer T-shirts, tanks and camisoles, knot-front knits look perfect in pastels and bright colors but, as usual, basic black works well with everything! These are the perfect sassy solution to the not-hot-but-not-cold weather that can leave us in a conundrum in the morning. They're also great during the summer to prevent air-conditioner freeze. Here, this lightweight luxe sweater from Urban Outfitters ($32) is flirt worthy and wallet friendly. Available at UrbanOutfitters.com.
