The lookbook for Vivienne Tam’s fall 2009 collection brings to mind crisp blue skies and nippy mornings, with nature’s glorious colors putting on their own fashion show. The tweed jacket and skirt shown above manage to be just as work-appropriate as the boring old suit-with-floppy-tie-blouse look that reigned in the 80s, but they are much more feminine and interesting. The contrast of the thick tweed with the sheer blouse is a genius move that allows the wearing of hefty tweeds while the weather is still too warm for fall sweaters under jackets. And of course, you can’t go wrong with the combination of black stockings and black shoes, which have been visually elongating legs for years now. No wonder they’re classics.
