Hilary Duff is such a die-hard fashionista, that she even matched her $2,000 Goyard St. Louise tote with her low-key gym attire!
The new mom-of-one has been on a serious mission to drop the baby weight in time for bikini season, and she's been hitting up the gym nearly every single day.
Over the holiday weekend Hil and hubbie Mike Comrie left baby Luca at home for an adults-only weekend in Sin City, and enjoyed a full night of partying in the VIP booth at Surrender Nightclub in Encore at Wynn Las Vegas.
Is it just us, or is Duff getting trimmer by the day?
