Lady Gaga's album sales are already stratospheric, so why not her evening wear?

The "Applause" singer unveiled a high-tech, white vehicle she bills as the world's first flying dress. The contraption lifted her up inside a mammoth building at the Brooklyn Navy Yard, where she held a launch party for her new album on Sunday.

The battery-powered dress has six booms in a hex formation.

The 27-year-old New York entertainer said later that this was "maybe a small step for Volantis" - as she calls the metal dress - but "a big-time step" for Lady Gaga.

She says her ultimate goal is to stage the first musical performance from space.

Her third studio album, "Artpop," will be released worldwide Monday.
