Vera Wang, 74, credits her ageless looks to vodka and daily McDonald's

It has long since been established that Vera Wang looks bloody fab - but what does she do to look that great?

The fashion icon, who is best known for her iconic wedding dresses, has seemingly discovered fountain of youth - but that doesn't stop her from enjoying some of life's simple pleasures.

Now, while it's no doubt that Wang looks absolutely incredible - it is important to remember that ageing is a totally natural part of life that should be embraced.

However, with that said, the 74-year-old fashionista has credited her ageless looks to two things I'm sure few of us are strangers to - some fast food and a cocktail.

Speaking to Page Six Style at the DKMS Gala in NYC on Thursday night (19 October), Wang revealed: "I do eat McDonald’s, absolutely."

She continued: "I order it every day, like two weeks on it, and then I’ll change."

But it's seemingly not just Maccies, as Wang says she also gets a hankering for Dunkin’ Donuts.

"I like the cream-filled, sugar-coated donut," she shared. "It’s like a jelly donut, but it’s cream inside, vanilla cream. I like the pink with sprinkles, too."

Of course, it’s not all Big Macs and donuts for Wang as she has previously explained that working hard keeps her youthful.

The New York-born businesswoman revealed she has never thought of 'going way out of [her] way' to 'preserve youth in a fanatical, obsessive way.'

"It's very complimentary and I am very grateful for that. But, I have been asked; what are my 'secrets'," she told BBC 100 Women last year.

"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."

Wang has also said that she thanks her 'magic elixir' which helps her keep so young.

"I always said that vodka cocktail, a lot of sleep, but work - work is the magic elixir," she added.

Talking about her approach to her diet, where she champions balance and moderation, Wang once told Harper's Bazaar: "I go through phases with what I eat for lunch.

"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."
