Vera Wang continues to shock people with her youthful appearance, with some joking that she's 'ageing backwards' after celebrating her 73rd birthday in June.
While a lot of it is down to good genes, the iconic fashion designer has shared a few tips over the years on how she manages to stay looking so much younger than her age.
And you'll be pleased to know it doesn't involve punishing yourself with a strict diet and hours at the gym.
The New York born businesswoman elaborated on her secrets in an interview with the BBC as part of its International Women's Day coverage earlier this year.
Alongside a suggestion to get enough sleep, Vera revealed that she 'values' having a vodka cocktail at the end of the day as it helps her 'transition from a very intense work schedule' to a 'bit of a private life'.

She also attributes her work in fashion to her youthful look, saying: "I've been in fashion since I was 19 years old. Not in front of the camera, behind it.
"I never thought about youth, probably because I work with the most beautiful women in the world on a daily basis. And because of that I more envision them as my muses, and maybe it's a way of dealing with ageing that is productive."
She continued: "So I always said that vodka cocktail, a lot of sleep, but work - work is the magic elixir."

As for Vera's workout routine, she revealed in a 2016 interview with Harper's Bazaar US that she focuses on exercising little and often.
"I usually lift weights, not much - two pounds and three pounds. It takes me a total of five minutes," she explained.
The fashion star also enjoys a spot of golf, telling InStyle at the time: "I'm not a huge exercise person, but I love to play golf at Liberty National, in Jersey City, NJ or at Atlantic Golf Club in the Hamptons if I happen to be out there.

"I'm terrible but enthusiastic."
When it comes to food, Vera takes a similarly laid back approach, stating that she 'never misses a meal' as she has to feed her brain.
"I go through phases with what I eat for lunch," she added. "I like sashimi with brown rice and vegetables, Chinese steamed broccoli with chicken and rice, or the artichoke salad or fish from Sant Ambroeus.
"At one point I was eating a slice of Ray's pizza every day, and I never gained a pound on it. It's not a bad thing if you squeeze out that excess oil. It's so filling.

"I only drink water – I stopped drinking Diet Coke six years ago. That was the hardest thing I ever gave up."
Last but definitely not least, Vera always makes sure she's donning the right eyewear throughout the day, from sunglasses in the sun to blue light specs when working on the computer.
Speaking to The Strategist earlier this year, she explained: "Eyewear is not only decorative or ornamental or a creative expression, it’s protective. You have to save your irises and pupils.

"And we’re all staring at screens all day – we need to be mindful because the damage will catch up to us eventually."
