Throwing at party at Up & Down generally means one thing. “This is a clusterf--k,” a guest, clearly uninitiated, said on Tuesday night. Indeed, there’s an inherent, built-in weariness to attending a party at the oft-booked venue, at least to the crowd-averse. But nonetheless, Dior had fashionably transformed the spot into the one-night-only "Poison Club," to celebrate the launch of their latest fragrance, Poison Girl, and thanks to cocktail servers spritzing the fragrance around the room, the club, while sweaty and packed, smelled quite pleasant.

The high volume of lithe models and equally skinny aspiring models (a melange of chokers, faux fur trim and contouring makeup) made the crush slightly more tolerable. Toni Garrn and Lindsay Ellingson took selfies together in one corner; Lexi Boling wandered around; Ophelie Guillermand was led through the crowd by DJ boyfriend Cedric Marian Alexander.

“It’s fashion week,” she shrugged when asked of the couple’s Valentine’s Day plans. Fellow Dior girls Dianna Agron (“It’s light, it’s sexy,” she said of the scent) and Keke Palmer (“I’m a Dior Barbie tonight,” she said of her look. “Dior clothes, Dior jewelry, Dior makeup, Dior perfume.”) were also there.

But the Bella of the ball, if you will, arrived around 11:30 p.m. and settled into a booth towards the back of the club. “I’m just here for Camille,” she demurred, holding court among her entourage, including her perpetually-hoodie-clad brother Anwar (the hood of choice for the evening was black).

The “Camille” she was referring to was model Camille Rowe who stars in the Poison Girl campaign. She was perched on the other side of the room. “I love how they gave me this table so I can just stare at myself all night,” she cracked.

In front of her the campaign video was projected on window blinds, vibrating from the club’s base-heavy playlist. “My friends aren’t here yet so I’m just sitting here alone watching myself. That’s normal,” she joked. The model was of course sporting Dior Spring 2017, her shirt “We should all be feminists," all the more topical now than when it first came down the runway.

“These are times we should all be together, as women,” said the model, who furthered the statement by wearing the look braless. “And I love that we’re all realizing that we need to get our asses up. And realizing that it takes more than a hashtag to change the world,” she said, then set down her tumbler on a napkin, emblazoned with “#iampoison,” and got up to dance.
