If you're in love with the lace slip dress trend that the Louis Vuitton Fall 2013 show sparked (hmmm, satin dressing-gown coats and lingerie petticoats…) then get ready for the winter-friendly way to wear it. We love the mix of a delicate fuzzy sweater next to a slinky lace petticoat that Spanish blogger Saray Martín has got going on, but the thing that really makes this on the money is her long sweater (think mini-dress length), revealing just the right amount of lacy slip underneath. With coat and skirt hemlines getting longer, it was only a matter of time before the sweater caught up. Say yes to the sweater dress!
