“Don’t bath more than once a week” — Designer Vivienne Westwood says

Flamboyant fashion designer Vivienne Westwood revealed the secret of her eternal youth only taking a bath once a week.

The 76-year-old queen of punk fashion let it slip after watching her husband Andreas Kronthaler’s spectacularly idiosyncratic show at Paris Fashion Week.

Asked by reporters how she managed to look so young, Westwood smiled and said, “Don’t wash too much.”

“She only takes a bath every week. That’s why she looks so radiant,” said Kronthaler, who Westwood has described as “the world’s greatest designer”.

“I only wash once a month,” joked the Austrian-born creator, who is 25 years Westwood’s junior.

Westwood, an environmentalist and vegetarian who has campaigned against the meat trade depleting water supplies, has previously said that “I just wash my bits and rush out in the morning and more often than not get in the bath after Andreas.”
