AT THE ATM: Designer Tony Melillo launched his new apparel brand, ATM, at Barneys New York in Beverly Hills at an event recently. ATM T-shirts, priced from $58 to $82, are available exclusively at Barneys for a year. “They really know how to market you,” said Melillo of the department store. “The most important thing for the first year is to just establish yourself in the right way. I had no interest to do it and sort of just throw it out there everywhere.” ATM has already become a favorite of Melillo’s longtime friends Kevin and Stephen Huvane, who hosted the event. “There’s a very relaxed sensuality to his clothes,” said Stephen Huvane. Ten percent of the proceeds from sales of ATM merchandise during the event went to amfAR.
