The 4 Must-Have Pieces for Fall

The Black Skirt: Evening

Weez's favorite skirt shape is the pencil because it's so slimming and elegant. Besides, she's a fan of clothes that "go easily from day to evening," and this sexy, side-slit style (Victoria's Secret Catalogue, $59) certainly qualifies. A glamorous double-breasted silk taffeta top with puff sleeves (Rickie Freeman for Teri Jon, $320) makes these separates as party-worthy as a drop-dead dress.
