Baby North West — Saturday’s Child and the offspring of Kim Kardashian and Kanye West — has been initiated into the cult of the hip cat flat. Charlotte Olympia sent N.W. a tiny pair of her kitty-face shoes for Christmas, and a host of other designers gifted their shoes and outfits to the baby girl. Giuseppe Zanotti sent white leather fringe booties, and Hermès sent a pair of silken pink booties and a matching blanket, so N.W. can rock some rocking horse motifs. Stella McCartney sent three hip onesies and two pairs of lamb mittens. And forevermore, North West will believe that Santa’s cobbler elves are the most stylish designers.
