Body jewelry for The 500 guests seemed nonplussed by the sponsorship. "I'm guessing it has a lot to do with our environment and how special our planet Earth is?" Tyson Beckford, the pillow-lipped male model, speculated, when asked about the rare earth connection. "I'll have to Google that when I get home."

He would have to wait. Despite the party's advertised start time of 7 p.m., the museum's nine floors were largely empty for the first several hours. The top level body jewelry held an intimate dinner for the museum's board members, while most folks drifted to the second and seventh floors, where champagne, vodka cocktails and Red Bull were served, and art pieces by emerging designers, photographers and artists were up for sale.

An early arrival was Alison Brie, the television actress ( "Mad Men," "Community"), who eyed a piece body jewelry by Tom Fruin. "I love the neon noose," she said. "But it might send a weird message if I have it hanging in my house."

The young designer crowd began pouring in at 9 p.m. Mr. Ahluwalia chatted with Vena Cava's Sophie Buhai and Lisa Mayock. Bliss Lau explained her fluorescent body chains; the body jewelry designer Eddie Borgo, in his trademark wide brim hat, cheek-kissed Jen Kao.

In keeping with the fluorescent theme, one duo flaunted colorful clown wigs, while another patron donned a neon pink bob, like the type you'd find on Harajuku girls. Staff members were also on hand to pass out glow-in-the-dark sticks, which were quickly fashioned into bracelets and eyeglasses.

With only two elevator banks, a small traffic jam formed on the second floor, where Paul Sevigny took over the D.J. booth, playing quirky retro tracks and crowd pleasers like Lady Gaga's "Born This Way."

Circling the dance floor was Mandy Coon, the fashion designer usually clad in black. "I've never been into neon, even when I was young," said Ms. Coon, who wore a colorful tunic. "But who knows, after tonight, maybe I'm ready for a revival."

At last all of then cheer for" I love body art, i'd love to piercing my ear with fashion body jewelry, like my navel rings."
