I’m not sure what pains me more—looking at this strange ensemble or having to trash Mary-Louise Parker.

As much as I admire the Weeds actress, I just can’t let this outfit slide. A baggy, army green dress coupled with blue-grey heels? Thank goodness her visit to the Late Show wasn’t scheduled for the same night as Anna Wintour’s appearance. I think Vogue‘s editor-in-chief would have had a lot more to talk about than David Letterman’s socks.
