Dianne Brill, a 1980s ‘It Girl,’ Makes a Splashy Return

When Dianne Brill arrived at the Soho Grand Hotel for her 66th birthday party on Saturday night, she did so with the same sense of spectacle that made her an icon of Manhattan nightlife in the 1980s.

People stopped and stared as she stepped out of a black S.U.V. Standing 6-foot-3 in white platform boots, Ms. Brill was wearing a silver satin wraparound dress and holding a glittering wand in one hand. Her hair was big and blonde, and she wore a big necklace that read “B-R-I-L-L.”

“I’m back,” she said. “Maybe not everyone knows it yet, but I am, and that’s why I’m having this birthday party. To show everyone I’m back.”

The party was billed as “One in a Brillion.” The dress code on the invitation was “Strictly Brill,” meaning the kind of thing Ms. Brill might have worn at nightclubs like Area and Danceteria four decades ago.

She came to New York at age 22 from the suburbs of Tampa, Fla. Soon she seized the mantle once occupied by Edie Sedgwick and Bianca Jagger as downtown’s reigning “It” Girl. She also became a muse to Andy Warhol, who once stated, “If you were at a party and Dianne Brill was there, you knew you were at the right party.”
