The hotel heiress told chat show host Craig Ferguson she was aiming for a modern-day Judy Jetson look in her grey dress, and appeared offended when he said she resembled a '1960s sexy air hostess'.
'Are these your shoulders?' Ferguson quipped as he stared at Hilton’s pointy pads.
'Yeah. I’ve been working out a lot,' the blonde socialite laughed.
Ferguson mocked Hilton relentlessly over her outfit throughout the course of his interview, which aired in the United States on Tuesday night.
Asked whether she suffered from stress, the former Simple Life star said: 'Who doesn’t?'
'You’re holding it in your shoulders,' the chat show host mocked.
'I’m never wearing a dress like this on your show again,' Hilton sulked.
Hilton also showed off her stiletto heels, which are from her own range of shoes.
The heiress pointed out that they were different from Christian Louboutin heels because the soles are pink - not red.
Hilton also agreed to play a mouth organ during her appearance on Ferguson’s show, but stressed she was not familiar with the instrument.
'Do I look like I know how to play this?' she laughed.
