“When in Rome” actress Kristen Bell looked simply stunning as she arrived at the “Geffen Playhouse” fundraiser in LA last night.

The weather is miserable in London, but Kristen has brightened up my day wearing an Alberta Ferretti Spring 2010 lilac apron dress.

I love the criss-crossing detail on the bodice.

I can imagine this dress fluttered beautifully when she walked the red carpet.

Kristen is quietly consistent on the red carpet.  She never tries to be edgy, just sweet, chic and sophisticated.

Her dress was paired with beige Brian Atwood Mary Janes.

This is definitely a BDOTW contender in my eyes.
