Sienna Miller and Gwyneth Paltrow both stepped out in NYC in chic off-white looks over the weekend, and both pumped up their ensembles with pops of red. Sienna made her first red carpet appearance since giving birth to daughter Marlowe in July at the Hamptons International Film Festival. The actress and new mom looked sleek and sophisticated in a white long-sleeved cape dress from Alessandra Rich, and coincidentally channeled Gwyneth's ultraelegant Tom Ford look from the 2012 Oscars. She kept accessories minimal, opting for a pair of gold metallic cuffs and a bright red lip-shaped clutch. Gwyneth made a stop at her friend Tracy Anderson's workout launch in an equally lovely, yet considerably more casual outfit — she paired an ivory Wes Gordon cropped knit sweater with a matching skirt from Misha Nonoo, and finished her look with a pair of red Sergio Rossi pumps.While both ladies flawlessly smack down that whole "no white after Labor Day" rule, their looks also prove how easy it is to add intrigue to ivory pieces by adding a pop of color — in this case, crimson.
