We have been counting down the days until payday to splurge on the new Rouje collection, and Sienna Miller just confirmed the one thing we want to buy. At a party in New York, Sienna wore the Momo top from Jeanne Damas's label, which has cute puffy sleeves, buttons down the front and a red floral print. And unlike most things on Rouje, it is currently in stock. She paired her top with navy high-waisted cropped culottes and a pair of brown leather pumps with a wooden heel.
