Do you eagerly await sweater weather, or do you get grumpy when the temperature drops and the leaves fall? Either way, be glad there are so many cute sweaters to buy. Whether cotton or wool, long or cropped, a sweater does the heavy lifting when there is a chill in the air. Go with a chunky-knit oversized one over a flippy short skirt for a girly-meets-grunge look. Boho and hipster types will appreciate a great vintage one in an ethnic print, like that sweet pullover they just saw on tumblr. Whatever your style, there is a sweater for it--even if (ahem!) Christmas sweaters are your pride and joy.
