If you can't make it to the event in NYC, don't sweat it: You can stop by any Madewell store from 6 to 8 p.m. to donate 25% of your purchase to Girls Inc. What's more, you can follow along with the fun via Instagram, and then enter here to win a $1K Madewell shopping spree, a signed copy of Pierpont's book, a custom print by illustrator Manjit Thapp, and a $1K donation to Girl's Inc. in your name. Paying it forward and getting what we want? Now that's how women get the job done.
