I Think Your Slip is Showing

Heidi Montag showed up to Letterman last night looking like the epitome of understated elegance:

Here's what CelebSpleak users thought about her ensemble:

Ellieinvogue says: Didn't this whole underwear as outerwear look go out a few years ago? She looks like she should be a Southern debutante lounging in her boudoir while she smokes long skinny cigarettes and walks around in feathered mules.

Jadaluvstarget says: Oh, poor Heidi. The dress bandit has come and removed her clothing again, leaving her to shiver in the cold wearing only an under slip. Spencer, quickly, give her your jacket before the little gal catches scarlet fever or gets mistaken for a lady of the night!
