Two pieces I think should belong in every wardrobe, a denim jacket and a solid color maxi dress.  I get so much wear out of these two pieces.  The maxi dress has gotten me through every season.  It's made from a heavier ponte knit so throwing on some extra layers has made it warm enough to wear even in the early stages of winter seen here.
