Posing in London’s SHOWstudio Shop beside the non-functioning white urinal she’d inscribed with “I’m not fucking Duchamp but I love pissing with you,†Lady Gaga wore a virginal white bra and a billowing crinoline skirt. The urinal, a straightforward homage to artist Marcel Duchamp’s legendary ready-made sculpture Fountain, is called Armitage Shanks and is, sadly for Gaga-loving Dada enthusiasts, not for sale. (More images of it here.) See the full ensemble in the Lady Gaga Look Book.
