Walking the line between good taste and risk is hard enough for a normal red carpet event, but when it comes to the Costume Institute Gala at the Metropolitan Museum of Art, it’s time for fashion critics (large and small) to be more ruthless than normal. You see, this event is sort of almost like Halloween – you’re supposed to go all out. And while the celebrity of your choice should look good, if they play it too safe here they’re just plain boring! (Such was sadly the case for far to many – from  model Gisele Bundchen in a tiny minidress, to model Amber Valletta in a simple tangerine colored dress. YAWN.

This year’s theme? The Model as Muse: Embodying Fashion

Sadly, Gossip Girl Leighton Meester goes on my list of ‘BAD’. She certainly made an effort. But she went overboard. She can’t seem to decide between an 80’s theme or being Shirley Temple. I’d personally pass on both. Verdict: BAD.

But LeMe wasn’t alone. In fact even the wonderful Heidi Klum had a ‘miss’ last night.

Heidi, you’ve been swallowed by a giant…uh…tattered bundle of cloth? I appreciate the drama, at least. Verdict: BAD.

Okay Hilary Swank, I get it. This isn’t a normal, boring dress. You’re sooo edgy. Or, you know, riddled with static cling! Verdict: BAD.

The dress and boots might have worked on Madonna. IF IT WEREN’T FOR HER HEAD GEAR. What is that, really now? A new form of scrunchie? Verdict: BAD.

Rihanna… *Giggle* Verdict: BAD.

Ashley Olsen, this is actually very well played! It’s unique and catches the eye. The back looks more or less like a white shower curtain, but the back is lovely. Verdict: GOOD.

Emmy Rossum (right)  usually sticks to classics and plays it safe. By sticking to a classic shape with a few flairs, she makes this dress work for the event. I would probably hate it for any other occasion. Verdict: GOOD.

Finally, one of these models gets it right! Good job, Miranda Kerr. This LBD is better than basic.

There is one thing I really like about Christmas (besides getting up my new Christmas tree today!) and that’s Santa hats. Everyone can look cute in a Santa hat. How cute does Heidi Klum look? She was on the Today show this morning collecting gifts from everyone in the audience. It’s great that kids that can’t usually get presents can from things like this.

Robert Pattinson did Jay Leno the other day. Robert seemed kinda overwhelmed. And when he looked at Heidi Klum he was trying to get her in his charms. And that hair. He kept running his hands through his hair every couple of seconds. My favorite quote…he said he has he doesn’t have a great sense of hygiene or style.

It’s okay, only Robert can get away with not washing his hair for like ever. He can still bite me if he wants.
