It had been reported that a female passenger stunned commuters when she got on the subway wearing nothing but leather boots.
The woman has now been revealed to be 38-year-old Eva, according to the Austrian Times.
A friend told local media: "She is a happy-go-lucky kind of person and likes to have fun. It was either a spontaneous idea, or perhaps she lost a bet.
"She is usually blonde - it seems she dyed her hair for the occasion."
Despite Austria experiencing snowfall and close-to-freezing temperatures, witnesses at Kardinal-Nagl-Platz station had previously stated that she didn't seem fazed by her lack of clothing.
