A new Hollywood "it girl" has arrived! Allison Williams has been making the rounds at award shows, premieres, and galas galore!

Just last week, the young budding star attended the 3rd Annual Sean Penn & Friends HELP HAITI HOME Gala Presented by Giorgio Armani at the Montage Hotel in Los Angeles, California.

Williams stopped for photos, decked out in a fabulous gold and white cocktail dress, complimented with equally fabulous makeup, courtesy or celebrity makeup artist Gita bass.  The makeup artist broke down her look for us, detailing everything she used to enhance Allison's natural beauty.

I call this look "my obsession with rose gold continues," Gita explained. "It's been my favorite shade lately and it works with every skin tone. Allison's dress was nude with gold accents and I wanted to warm up the face and keep the look soft and sexy."

"For a flawless complexion I prepped her skin with Simple Protecting Light Moisturizer ($11) and applied a few drops of Armani Maestro Foundation ($62) and Cle De Peau Concealer ($70) where needed," said Gita. "I applied Chanel Le Blush Creme De Chanel cream blush ($38) to the apples of her cheeks and set it with Nars Powder Blush in Deep Throat ($29)."

"For the eyes, I lined upper, lower and inner lash lines with a chocolate eye crayon like Osmosis Colour Eye Pencil in Brown ($12) and smudged it with a soft brush. I then applied Chanel Illusion D'ombre ($36) in Abstraction, a gorgeous warm rose color, to the lid up to the crease and on the lower lash line," Bass said.

"To create the rose gold, I layered the bronze shadow from the Lorac Baked Eyeshadow Trio in Superstar ($27) over the cream and used the light gold for the inner corners and brow bone. I finished with a few coats of YSL Mascara Singulier in Deep Black ($30).

And wondering what lip color Allison is wearing? "For a soft peachy nude that would add warmth to the face, I mixed Tom Ford Lipstick in Blush Nude with a touch of True Coral ($49 each)."

Doesn't Allison's look great? Nice work Gita!
