The This Morning host went all out in 70s glam for the Studio 54 theme when she attended the Annabel's 4th anniversary party in Mayfair.
Willoughby, 41, stunned in a maxi, multi-coloured sequin dress by Attico, fully committing to the dress code for the celebration. The designer dress’ thigh-high split allowed the TV presenter to show off her equally glamorous Terry de Havilland peep-toe platform heels, which were also covered in sequins.
The mum-of-three paired the blue, purple, green, pink and gold dress with a bright orange feathery shawl thrown over one shoulder, and finished off the outfit with large Elton John-style bejewelled sunglasses and a Rixo shell bag.
Joined by her husband Dan Baldwin, Willoughby kept her signature blonde hair in its usual flawless waved bob, and added some colour to her make-up, with a pale blue eyeshadow. TV producer Baldwin didn’t hold back either on adhering to the dress code, in a beige knee-length coat with fluffy cuffs and collar, which he wore over an all-black ensemble.
Annabel's is one of the most exclusive members' clubs in the UK frequented by celebrities, aristocrats and royalty. The Mayfair hotspot welcomed celebrities from Penny Lancaster to Naomi Campbell for the glam 70s themed night, in honour of the iconic New York club, Studio 54.
Models Lancaster, 50, and Campbell, 51, showed off their fashion chops with equally glam outfits for the occasion. Lancaster opted for a sparkling silver mini dress and white thigh-high boots as she joined her husband Rod Stewart, and Campbell slipped into a flowing black and gold diaphanous dress as attendees partied into the night for the star-studded bash.
