Jennifer Aniston used to wear a policeman’s hat while partying, reports.

The actress — who is often voted the world’s most stylish woman — admitted she made many fashion faux pas during the ’80s when she regularly visited New York’s all-night clubs.

She said: “I did have that period.” Aniston went on to describe her favourite outfit, which consisted of ripped tights, boots, a police hat and “maybe a bra.”

The 40-year-old actress — who also confessed to dancing on the clubs’ podiums — added to talk show host Jimmy Fallon: “No one should have let us go outside like that.”

Although her days of wild parties and fashion mistakes are over, Aniston recently admitted to worrying about something else — grey hairs.

The 40-year-old actress said: “I found a really long grey hair and it kind of flipped me out. It’s not my first but it’s the fact that it was so long. I was like, ‘Oh that’s been there. How many others are there, and what does that mean?’ It actually brought me to tears slightly.”
