The 37-year-old stepped out during New York Fashion Week on Thursday looking hotter than ever in a head-to-toe white ensemble. The actress was on-hand for the grand opening of Avra Madison, a new N.Y.C. Greek eatery, and showed off her impressive abs in the process. Holmes paired a soft wool off-the-shoulder cropped sweater with a pair of high-waist, wide-leg white trousers, showing off a hint of skin that is rare for the conservative starlet. Paired with a berry lip and a sleek blowout, this all-white outfit looked totally appropriate past Labor Day. The actress, who is mom to 10-year-old Suri Cruise, was clearly into her chic look, taking to Instagram to share photos from the event. In one ‘gram, Holmes does an expert hair flip, demoing how she truly got that perfectly blown-out look from hairstylist Jed Root of Serge Normant Salon.
