All jokes aside, I can't vouch for whether that's real or not, so I'm going to leave that out of the equation and just note that it's amusing to me that she is embracing Snow Monster Glam. The Bumble would be so hot for her.
The dress underneath is fine, too -- she looks very nice, very lively, perhaps a wee off-kilter; basically just the way we like Emma. It's an attempt at fancyness but not so fancy nor perfect that we don't still imagine she's a killer hang.
She also brought Greg Wise and their two children, one of whom is the Rwandan refugee they adopted when he was sixteen. It seems to have worked out well for them and they're rarely all seen together, so: VOILA. I'll shelve my rant about shoe choices for another day. I'm not made of stone.
