Krysten Ritter did an appearance on 'David Letterman' on Tuesday in NYC.
The 'Don't Trust the B---- in Apartment 23' actress wore a sapphire coloured, off-shoulder dress from the Z Spoke by Zac Posen Spring 2012 collection.
I thought the colour was great on her and if you're wondering about her hair, she left it down for the taping! Her look was completed with jewelled Jimmy Choo sandals.
