New mom Hilary Duff is really trying to keep that hard-earned size-26 booty, as evidenced by a surge of paparazzi shots in Yoga-ready ensembles. This time, however, the Disney darling almost had us fooled. She tossed this rag & bone Distressed Leather-Sleeve Jean Jacket ($495) over her leggings-and-tunic combo post-Pilates last Wednesday before heading to Paper Source in Los Angeles for some festive wrapping paper. So, we have learned two things: One, Hilary Duff is magic, and actually does things after a workout. And second, she looks cute doing those things (leather sleeves are a major trend!). What’s your secret, Hil? Endorphins? Ehh.. we’ll pass.
