Dear womens' wear designers: We have an urgent plea. It's getting colder, and those of us without town cars are freezing whenever we walk to the subways, the parking lots, or the bus stops. Your clothes are not helping. The open-toe-and-tights trend looks so chic, and hurts like hell in the wind. The beaded a-line dresses give incredible holiday shimmer, but their stones freeze cold against our skin. Cropped motorcycle jackets are not very warm, even with those amazing scrunched cashmere gloves that go with them. But you know what's really warm? Flannel lined jeans. We wore them across our prep school campus in 10 degree weather, and survived. We crashed in them during ski breaks. We slept in them while camping. It would be so amazing to wear them to work with a cute blazer and heels. But right now, the only pair come from L.L. Bean, and look like they were cut especially for uncool moms. Womens' wear designers, please study these jeans and then make them in a chicer cut - a lower waist, a slimmer leg, a boxy flare, something. Like Luella Bartley's Gisele bag, a hot pair of flannel lined jeans could be your best selling item ever. Please, get going - we're freezing over here in our little shrunken jackets from Miu Miu!
