Jenna Ortega evoked her Nevermore Academy schoolgirl character Wednesday Addams in an ensemble hand-picked by designer Thom Browne for his 20th anniversary dinner at The Grill in Midtown Manhattan on Monday.

The 21-year-old former Disney Channel star wore girlish white knee socks with a silver-sequin patchwork shorts suit over a screen-printed necktie-and-collar top, and patent leather platform booties.

Jenna - who wore her brunette locks down - toted a matching Thom Browne patterned purse and wore statement earrings.Ortega flashed a dimpled smile with a minimally made-up complexion and only a bit of mascara and sparkly shadow to bring out her brown eyes.

The Emmy nominee made sure to pose with the 58-year-old man of the hour, who was promoting his self-titled 420-page monograph published by Phaidon Press last Wednesday.

hom - who calls Jenna 'my birthday twin' - famously enlisted her to represent his American fashion house at the Met Gala celebrating Karl Lagerfeld: A Line Of Beauty back on May 1.

While at the cocktail party, Ortega mingled with The Real Housewives of New York City star Jenna Lyons - who opted for a traditional blazer over a pleated skirt, calf-high socks, and wingtips.

Everyone there was suited and booted including Brooklyn singer King Princess and Highsnobiety editor-in-chief Willa Bennett.The Adidas brand ambassador also caught up with Rosaline actress Isabela Merced at the fashion festivities.

At one point, Jenna was seen aiming an old-fashioned camera at a dapper partygoer while perching sideways in her seat at the dining table.
