Housing Formichetti’s latest work – he’s also the creative director at Thierry Mugler – the Walker Street shop includes several outlandish ensembles he’s fashioned for the pop icon.

Mimicking one of Gaga’s dazzling funky fractal costumes, the surfaces are made up of hundreds of CNC-cut, mirrored plates (attached to each other using aluminum clips) mounted to lightweight composite structural backing. The jagged pieces strike out from the ceilings, walls and floor of the four-metre-wide by 21-metre long space.

The concept was inspired by Jan Van Eyck’s famous painting The Arnolfini Wedding, which depicts the marriage of an Italian merchant. “I like how in one image, you can see the front and back of the clothing the couple is wearing,” says project architect Mark Foster Gage (who also teaches at Yale’s architecture school), “We took this idea to its logical extreme.”

Wth mirrored sheets covering the floor, there’s a dressing room likeness only Gaga and her trunk of monstrous heels can appreciate (the flooring is appropriately abrasion-resistant). Formichetti’s funhouse doesn’t stop there. Gage/Clemenceau have also constructed giant suspended acrylic coffins that function as displays for Gaga’s stage costumes.

Architects for Gaga isn’t new. Like Frank Gehry, who designed a hat for the singer, Gage/Clemenceau is reportedly working on a costume for the performer that is made up of series of 3D masks that feature 25 of her Facebook fans.

Nicola Formichetti’s pop-up shop on 50 Walker Street is open until September 12.
