We've been fans of Armarium, the luxury-on-loan styling stop and service for NYC It Girls forever. Last week, we joined founders Alexandra Lind Rose and Trisha Gregory to celebrate their new app.

Walking through the dimly lit candlelit entrance of 583 Park, guests were greeted by waiters in uniform carrying silver trays adorned with champagne flutes. To say this event was well attended would be an understatement. With a fully stocked bar front and center, it was wall to wall packed with the city's who's who along with a few Victoria's Secret models sprinkled in. You may think it doesn't get more glam than this, but we haven't even looked up... An ornate crystal chandelier brought the space together with elaborately dressed mannequins artfully hanging on its flanks. The combination of downtown cool and uptown embellishment was finally reached in a prime kickoff to this spring social calendar. Will you #JoinTheArmi?
