Giorgio Armani - One Night Only NYC

Stylishly clad stars collided at Giorgio Armani – One Night Only New York, held yesterday at SuperPier in New York City, with many, of course, trotting out mainly monochromatic looks from the event’s namesake designer.

Renee Zellweger: The actress skipped the skirt and suited up in a black, bow-accented blazer and loose trousers. Her minimal styling and barely-there makeup contributed to the more mannish aesthetic.

Hilary Swank: Also wearing the pants to the party, Hilary took a more dramatic approach with her slim-line pair worn with a glittery, nipped-in blazer top, further vamping up the look with strappy sandals, a smokey eye and loose waves.

Naomi Watts: Playing with proportion, the ‘Diana’ actress pulled off a silken, charcoal-grey top with billowy sleeves paired with a loose, floor-scraping black skirt. There was a lot of fabric to be had here, but there was still an effortless elegance with her swept-back locks and gemstone Monique Péan earrings.

Olivia Munn: Looking lovely, but really quite leggy, Olivia tried a pair of black mini shorts on for size, which she wore with a black silk halter top and a monochromatic cape slung over her shoulders. Black peep-toe pumps, a swept-back bun and a punchy coral lippie completed her sultry, skin-is-in entrance. Bold and beautiful, or no?

Olivia Palermo: The stylista was significantly more covered up in a mainly black statement, with her accessories once again making all the difference. She complemented the look with strands of gold necklaces and a few bangles, along with a black cummerbund belt and forest-green lace-up shoes, throwing a blazer on for that final flourish.

Dianna Agron: The ‘Glee’ girl also followed the black theme of the evening with a long-sleeved, empire-waist coat dress, accented with two rows of buttons at the bodice. A pretty, bronze smokey eye and pink lip, along with half-up, half-down blonde wavy locks, added a radiant note to her all-black ensemble.
