"I'm happy to support a new designer," the actress—in her first post-baby appearance—told InStyle.com. The look reminded us of Gwyneth Paltrow’s statement-making Tom Ford gown for this year's Oscars. (They both even accessorized with big cuffs!) "The Oscars is the biggest nail-biter," Paltrow had told us of this look. "I've learned to wear what works for my body while always taking a bit of a risk. This Tom Ford gown was stunning and modern and recalled a kind of '60s glamour." Do you like the cape style?
