Fashion designer Vivienne Westwood has revealed that washing just once a week is the secret to staying young.

Speaking after the Andreas Kronthaler for Vivienne Westwood Spring/ Summer 2018 show during Paris Fashion Week, the 76-year-old advised that people shouldn’t “wash too much” when reporters asked about her youthful appearance.

Her husband, Kornthaler, 51, then interjected saying, “She only takes a bath every week. That’s why she looks so radiant,” before revealing the he cleans even less often.

“I only wash once a month.”

This isn’t the first time fashion’s nonconformist queen has opened up about her bathing habits, or lack thereof.

“Normally at home I’m not used to the habit of a shower,” she previously said.

“I just wash my bits and rush out in the morning and more often than not get in the bath after Andreas.”

The environmentalist also starred in a campaign for animal rights group PETA, which shows her having a shower.

In the clip, she explains that her decision to become a vegetarian wasn’t just because the meat industry is the “worst polluter of the planet” but also because it “squanders most of our waters.”

Despite being considered the grande dame of fashion Westwood’s ‘scruffy’ style has often come under fire but, while her unique image isn’t for everyone, the designer says people have never looked so ugly as they do today.

Criticising disposable fashion and consumer habits for buying quantity over quality, she previously said, “Everybody looks like clones and the only people you notice are my age.

“I don’t notice anybody unless they look great, and every now and again they do, and they are usually 70.

“We are so conformist, nobody is thinking.”
