What Did Blair Wear? (Episode 3.11: The Treasure of Serena Madre)

I actually like this whole outfit--a sad rarity for season three Blair, unfortunately. She wears a navy Marc by Marc Jacobs moleskin coat, gray lace tights, and a red Anya Hindmarch large Belvedere bag.

Here's another view of the coat that shows off the adorable full skirt.

On a hunt to discover Eleanor's secret, Blair stalks the mail in a navy and black Rachel Comey Patron Scout dress.
B shows up with a platter of treats for Thanksgiving dinner in a seasonally colored Last Tycoon coat by Nanette Lepore.
Underneath, she wears a Sariah NYC dress, black lace vine print tights, and black Pour la Victoire Petra high heel zipper strappy sandals.
