"We bought a bunch of things in the Hamptons," Siriano says. "We got some knickknacks and lamps from a store in Paris. We love the Chelsea antiques."
"We've had stuff shipped from this store, Pom Pom Interiors in L.A.," Siriano says. "There are some pieces from my first apartment. It's a mix."
Among the antiques, Siriano and Walsh have added modern accents and pieces passed down from family.
"We have all these eclectic things. Putting them together is a game," he says.
Some might hesitate before incorporating a fur serving tray and an animal-skin rug in a living room filled with antiques. Not Siriano. He loves to decorate with rich texture.
"It's like a styling job," he says. "Taste is really important."
The showroom and anchor of the apartment is the living room, a spacious area reminiscent of a museum, with its perfectly spaced, opulent-looking paintings, antique chairs and bird cages.
"People are so intimidated by this room. They are afraid to sit down," Siriano says as he plops down on the massive plush couch.
Siriano pointed out two French-style chairs that he purchased from a dealer in San Francisco.
"I just love them," he says, laughing. "They were my first purchase after winning 'Project Runway.' They cost so much, I couldn't buy anything else after that."
The kitchen contains several of the couple's favorite pieces.
The first is a framed painting of the two that sits atop a row of cream-colored cabinets. The artwork, by local artist Barnaby Ruhe, took 15 minutes to whip up.
"He really captures you," Siriano says.
Walsh, a DJ, music producer and photographer, points out a red metal bread box, which they purchased online from an antique store. He saves his absolute favorite — a yellow 1970s Syndicate Manufacturing recipe box — for last.
"It's from 'Grey Gardens,'" Walsh says, revealing the couple's love of the documentary about eccentric Jackie Kennedy relations on Long Island. "It's the same one that Edie Beale gives her mother that contains the wedding jewels."
"It's really hard to find. But I found this on Etsy for $8."
Walsh's favorite area in the apartment is a loft-like space that he uses as a studio to create music and work on artistic projects.
"I'm not really allowed up there," Siriano says with a laugh.
