Dame Joan Collins has never followed beauty trends

She said: "An actress friend of mine gave me some advice years ago.

"She said, 'You don't have to follow trends or fads. Find something that suits you in your 30s and stay with it.'

"So my make-up hasn't changed that much. I still wear bright lipstick and I have a great collection of them."

Joan is known for her glamorous image and she never felt more beautiful than when she was starring in 'Dynasty' as Alexis Colby.

Asked when she felt she looked her best, she said: "The 80s when I was doing 'Dynasty', I came into my own in terms of my looks. I was on 600 magazine covers, so I was quite pleased with myself."

But the 'Time of Their Lives' star admitted she spent years feeling insecure about her appearance because of the harsh comments of Hollywood producers.

Discussing advice for her younger self, she told Britain's OK! magazine: "I wouldn't be as insecure about my looks as I was then. Studios make you feel very insecure.

"You're too fat or too short or your hair was too straggly and thin. You really get put through the grinder.

"Eventually I started looking in the mirror and thinking, I'm not so bad after all."

Joan has to travel a lot for her work and has perfected stepping off a plane looking glamorous and fresh.

She said: "I always change into something comfortable - they have great sweatpants made of cashmere at Marks and Spencer and a zip-up top.

"I take off my make-up and I do drink a lot of water but I also drink quite a bit of wine.

"I try to sleep and at the end I put on my clothes, make-up, sunglasses and a hat and then stagger out."
