Demi Moore put on a brave face and stepped out for the premiere of Margin Call on Monday amidst the allegations surrounding her marriage. For the occasion Demi opted for an elegant red patterned pencil dress by Zac Posen. She teamed the dress with black satin Brian Atwood pumps and a Christian Louboutin clutch. It goes without saying that Demi looks on the thin side here and is making no attempt to hide it in this dress.
