December is 4 invitations in 3 weeks: the office party, the client dinner, a friend's house, and New Year's Eve. These 63 pieces, from $160 to $910 in sizes 0 to 16, are 21 dresses, 5 jumpsuits, 14 blouses and tops, 4 blazers, knits, 6 coats, and 3 clutches, chosen so that 2 dresses and 1 coat cover the whole month.

For the party where you are photographed, the Iris champagne gold cocktail dress or the Dora feather trim dress. For the dinner, the Jody lace cocktail dress in midnight green or bordeaux. For the house, the Talia satin blouse with Agatha wide-leg pants. For midnight, the Laura bronze metallic. And over all of it, the Lucy wool coat with the faux-fur collar in black or red, or the Selina cape.

Every piece is made in our atelier in Pozarevac, Serbia. Dresses, jumpsuits, blouses, and blazers are machine washable on a gentle cycle; coats are dry clean only. Each page shows the sizes in stock today. Orders ship from California within a business day. Returns are free for 30 days.
