A wool coat can't be beat in the winter, but if you're like me, then you don't have upwards of $300 to spend on a coat that is both chic and functional. I learned last year that a change of buttons can make an affordable coat look expensive. And also that a coat in a non-bulky wool will keep you from overheating when you layer. A fleece vest, like this one from L.L. Bean, will also keep the wind at bay. Elbow-sleeve gloves make a three-quarter sleeve coat more functional too. These are just a few tips to keep in mind as you browse through the following wool coats--all priced at $150 or less.
