Jack McCullough and Lazaro Hernandez of Proenza Schouler hosted the party of the week in New York city on Monday night,  when they invited their collaborators and friends to toast the US launch of A#9. Their choice of venue was a townhouse in Soho Mews, the new luxury condo development in West Broadway.

The crisp pages of their ‘Made in the USA’ edition were showcased inside the townhouse for guests to see the beautiful work of the designers and their collaborators, including that of performance artist Kalup Linzy (who was also in attendance).

And what would the A#9 NYC party be without it’s cover girl, the divine miss Chloë Sevigny? She dazzled in a Proenza Schouler leather belted jumpsuit, exclaiming “I feel a little bit like a super-slut superhero!”

Other guests included cover photographer Richard Burbridge, Derek Blasberg (who interviewed Bruce Weber for a piece in the issue) and Yvonne Force Villareal of Art Production Fund, the veritable ‘force’ behind much of Proenza Schouler’s brilliant spectacle in June at Pitti Immagine in Florence, Italy.

The party was as low-key an event as such a New York society crowd permits, with beers in icebuckets and a tire swing on the terrace (albeit a designer one by Aaron Young of Cumulus Studios!). ‘Kids’ actor Leo Fitzpatrick and artist Nate Lowman hit the decks to dj for the event, as various art, music and fashion personalities enjoyed the summer evening sipping beers and champagne, including P.S.1’s  Tim Goossens, model Sigrid Agren, Vogue’s Hamish Bowles and up-and-coming young illustrator Aurel Schmidt.

Surely a last hurrah for Jack and Lazaro after riding a crazy wave in the past few months, culminating in the completion and launch of A#9, their reception of CFDA Accessories of the Year award, and their work with Pitti Immagine as the special guest of the womenswear pre-spring collection presentation. Congratulations guys!
