Olivia Wilde is a bonafide stunner, so it typically doesn’t matter what she wears. When I first spied her in this L’Wren Scott look at the premiere of her new movie “Deadfaull,” I loved it. But on closer inspection, it seems a little dowdy and mumsy. Like, I could see somebody’s grandma wearing it to a Christmas eve church ceremony. And maybe it’s not showstopping enough for a premiere. But what do you think? Is it a yay or a nay in your book?
