Earlier this week, Michael Kors opened his largest European flagship store on London's swish Regent Street. Naturally, the designer known for his luxury, jetsetter-approved wares celebrated in style—and with some very famous friends at his side. Peep the looks that some of Michael's glamorous gal pals wore, and get inspired for upcoming weddings, engagement parties, or after-work champagne soirees (aka Tuesdays.)

Model Arizona Muse kicked up her heels in a glittering fringed skirt from Michael Kors Collection, paired with a button-down blouse.

Jessica Chastain was spotted in, um, spots. The stunning redhead wore a belted shirtdress with a pleated skirt, and her hair down in loose waves.

Writer Camille Charriere looked every bit the chic Parisienne in a striped shirt layered under a slip dress.

Solange Knowles sparkled—and danced!— in her bejeweled silver pants. "Need glove. Need white socks," the singer wrote on Instagram.

Fashion blogger Gala Gonzalez wore a slashed top and skirt from the fall collection.

Elle Macpherson donned Michael's crystal-embroidered, floral lace, flared jumpsuit.

Gwyneth Paltrow was all smiles in a sequined dress by the evening's honored guest.
