Lace. One word, so many possibilities. Even though it tends to be a more summer fabric, its definitely works in the winter. You can put it over a different article of clothing so its not so revealing and warmer. Lace is so versitile, whether its a dress (like Nathalie is wearing above), a crop top, or scarf, its a great choice. Also, seeing as winter is coming up (so excited...) a great set of boots is a must. The one golden rule for boots is to use a leather protecter so they will last more than one winter. Just make sure its silicon based because alcohol base will dry out the leather and could stain them.
