Joan Collins may be 80 but when it comes to fashion she "won't be defined by age" and will wear a bikini if she wants to.
The former Dynasty actress also said that before the days of quality make-up and "tricks", Hollywood stars depended on good lighting in order to look beautiful.
"I won't be defined by age. I'll wear a leather skirt - even a bikini - if I want to. Clothes are my passion and I adore them.
"Some people today consider style, elegance and being well dressed and groomed as a frivolous waste of time, but not me," she told the Mail on Sunday's You magazine.
The octogenarian said make-up has "come on hugely", adding: " I remember when I was growing up there wasn't much make-up and there were no tricks.
"It was quite harsh, really. What the Hollywood stars relied on was fantastic lighting. I mean, I met Marlene Dietrich once, very briefly, when she was at the Cafe de Paris and I was about 18, and she was not that beautiful or tall or impressive.
"But her lighting in all her movies! If you see The Scarlet Empress or Shanghai Express, well, she made me look dowdy in comparison."
Joan, who recently appeared in TV series Benidorm, said it takes her half an hour to put on "a full face with lashes".
"I shove it on - that's why it's called slap," she said.
