Giorgio Armani was "endorsing a revolution" when he first started dressing celebrities.
The legendary fashion designer has been working with stars on their red carpet looks for over 30 years.
The 80-year-old is credited with starting the trend for suiting and booting the A-list, but he believes it was down to the 1980s being a time of change.
"The new establishment no longer saw themselves all glamour, sequinned and sparkling divas," he explained to British newspaper The Telegraph. "Celebrities wanted to wear clothing that enhanced them but were not costumes, and it was exactly the type of revolution I was endorsing in the fashion world."
The first starlet he dressed was Diane Keaton, who wore a beige jacket over a long skirt to the Academy Awards in 1978, where she won the best-actress award for Annie Hall. It's a look that the Italian is still proud of today.
"I thought it was time to represent women, even stars, in a new way," he said. "A woman in a masculine suit on the red carpet - well, I find it extremely elegant and sensual at the same time."
He went on to work with Michelle Pfeiffer in 1983, and the two have become firm friends. Other celebrities who have worn his designs on the red carpet include double Oscar winner Cate Blanchett, fellow Academy Award winners Jodie Foster and Julia Roberts, as well as Beyoncé Knowles and Lady Gaga. Giorgio gets as much out of how the wearer feels in the dress, as how it looks on the red carpet.
"What always gives me satisfaction is the natural way my clothing feels on those who wear them," he added. "They don't weigh the person down, but accompany and enhance them. This is how it was and is for Jodie Foster and all the stars I dressed and dress. But also for all women who love my fashion."
