There is only one place that a woman can get this look and that's as a bridal shower gift from her Aunt Carmella in 1979. We don't know if Lady Gaga has an Aunt Carmella who handed down this sexy nightgown, but we do know that 100% of women in the '70s wore this exact look during their honeymoon to Hawaii, including the hair.
So why is the "G.U.Y." singer wearing it on a street in Manhattan? The world may never know.
