Six pieces, even?

Our girl Brit wore a couple different outfits while shooting CBS' How I Met Your Mother, and now they're going up for auction reports The AP.

The clothing items - which include a Juicy Couture dress, Nannette Lepore dress and cardigan - will benefit the Natural Resources Defense Council.

Kudos for turning a TV event (the show airs tomorrow) into a charity event as well!
