Kristen Bell attended the World Premiere of “When In Rome” last night in LA.

The blonde actress opted for a chocolate brown Monique Lhuillier Spring 2010 gown.

I adore this floor length chocolate brown dress with cut out details and a rope like cord hanging from the midriff.

I’m pleased that Kristen has worn her hair back with minimal make up as I think the details in this dress speak entirely for themselves.

My only complaint would be that I would liked to have seen some heavier gold accessories worn with this rich shade of brown.

Long crystal earrings and a bronze clutch complete her look.

I like seeing this style of cut-out dress on the red carpet. Last year we saw Hilary Swank in a Monique Lhuillier Fall 2009 cut out dress which I really loved.
