To find the answer, you can check out the September 4th issue of PEOPLE magazine (Jonbenet Ramsey is on the cover, but that has nothing to do with me), or click here www.theskinnythebook.com. Or, when it comes out, you can buy The Skinny: How to Fit into Your Little Black Dress Forever (Meredith, December, 2006). It's the book I wrote with my brilliant friend Robin Aronson (the other skinny girl in the photo). To be honest, before PEOPLE called to interview me for this piece, I'd never even flipped through the magazine, not even while getting my hair done. Now I may just have to subscribe. Yes, I'm that happy. This picture above, by the way, is not from the PEOPLE photo shoot (Michael Lavine took the photos of me at restaurant Daniel). It's a publicity shot of Robin and me for The Skinny, taken in Des Moines at the publishers. But I'm wearing the same dress as in PEOPLE. Every girl should have a favorite little black dress, and this sample-sale-scored Chaiken number is mine. May the dry cleaner never shrink it.
