Q: I don't want to buy a whole glitzy outfit this season. Is there a piece that I can wear both at the office and to holiday events?
A: I agree: It's more modern to mix day and evening clothes, and more practical (who wants to schlep a dress bag to work—or go home and change?). It's also cheaper—a sparkly top to layer with office basics needn't be a big investment. After 5, retreat to the ladies', switch to dressy accessories and vivid lipstick , and you're transformed.
Cool and Sexy: By day, sneak a glittery tank (Tucker, $428; TuckerWebShop.com ) under a cardigan (Vince, $275, Saks Fifth Avenue; 877-612-7257). Drop the sweater for evening, letting color—orange trousers ($138; JCrew.com ) and gilded flats (Kate Spade New York, $225; KateSpade.com )—take over. Necklace, Sheila Fajl, $90; HSN.com . Clutch, JCPenney, $30; 877-346-3527 for stores.
