Her long hair, which had been blow-dried perfectly earlier in the day, fell in a side parting and still retained it's volume.

A pair of simple black heels perfectly showed of her toned legs as she strutted her stuff on the sidewalks of the city, after leaving Avenue nightclub where she partied with pals.

The stunning heiress was clearly feeling peckish after her exciting day, as a friend accompanying her carried a couple of boxes of pizzas, presumably for a late night snack back at her hotel.

Earlier in the day Tamara stepped out in a high-waisted plum coloured skirt, teemed with a sheer snakeskin-print blouse, a black clutch bag and matching platform heels.

During her time in the city, which is currently hosting Fashion Week, the brunette was spotted going out for dinner with a handsome companion, Scott Harvey-Nicholls, who is also her brand manager.
