As Michelle Obama stepped on stage with her husband in Chicago early on Wednesday morning, she accepted her role not only as First Lady but also as fashion tastemaker for four more years - this time, wearing a Michael Kors magenta silk chine pin-tucked dress.
Mrs Obama sported a dress pulled in at the waist and topped with a black shrug that showed a peek of a vintage pink brooch from House of Lavande.
She was surrounded by her trend-right daughters: Malia wore an electric-blue, A-line skirt with a pink studded belt that looks like the teen version of the First Lady's signature Azzedine Alaia belt, and Sasha had on an abstract-print green skirt, grey bow-front top and mimicked her mum's shrunken cardigan look.
Mrs Obama has been a reinvigorating force for the fashion industry, from her late-night online J Crew purchases to her savvy courtship with up-and-coming designers, including Prabal Gurung and Jason Wu.
Kors has been a consistent label in her wardrobe, with Mrs Obama wearing a black, racer-back dress by the designer in her official White House portrait, as well as a hot-pink gown for a White House Correspondents' Dinner and a red halter gown at a Congressional Black Caucus Foundation Phoenix Awards dinner.
"Mrs Obama looked chic and elegant as always on election night," Kors said.
"My dress, with its strong colour, clean lines and feminine silhouette, has all the elements that have become a part of the trademark style of our First Lady."
The Council of Fashion Designers of America gave Mrs Obama its Board of Directors' Special Tribute award in 2009 for her influence in the industry.
Four years ago on election night, she wore a straight-from-the-runway black sheath dress with splashes of red by Narciso Rodriguez.
