The Dog Fanny Pack. Is your dog feeling neglected after being left behind all week while you raced around the tents at Bryant Park? Here's the perfect fix in the form of this season's hottest accessory that we've already spotted on the runway thanks to Marc Jacobs. While this isn't practical for everyone's dog (Sorry Stanley, you'll have to take a few more laps around the block before we'll carry you around on our hip), it's perfect for small-sized fashionable pups on the go. And if it's good enough for MJ, then it's good enough for your pooch.
