You may not know the name Santo Loquasto, but you have most likely have seen his work. Loquasto has designed scenery and costumes for some of the biggest names in the business, and his skill sets ranges from classical ballet to Broadway, and from live theater to film--with a healthy dash of opera tossed into the mix. I met with Loquasto on muggy August day at the Margot Patisserie on 74th Street. A modest man with a dapper beard and killer smile, he sips an iced coffee while we talk; every now and then, he flashes that dazzling smile.
