When a lot of people – men and women alike – hit the big 5-0, their need to keep fit and appear super sexy goes somewhat out the window.

Not 54-year-old Carol Vorderman, however: she stepped out last night looking sexier than ever as she left Scott's restaurant in London's swanky Mayfair.

Sporting her new bright blonde locks, Carol re-wore a vivid green Roland Mouret dress – the same, headline-grabbing dress she donned back in 2005 to great acclaim.

The figure-hugging dress was from Mouret's spring/summer '06 collection which took the fashion world by storm with celebrities such as Cameron Diaz and Victoria Beckham wearing them to red carpet events. 

To update the look for a new decade, Carol teamed the slinky number with a chunky white belt and light khaki lace-up heels.

And we think she wore it better last night than she did ten years ago.

Carol has clearly been working out as the show-stopping frock clung to her tiny, gym-toned figure and for a woman her age (or any age!) she wasn't afraid to show off her body. But that's no surprise as recently she has been sharing snaps of her enviable physique on social media. All we can say is… fair play.

As many celebs these days would not dare to be seen in the same outfit twice, Carol is not afraid to re-use items from her wardrobe. She has stated in the past that she doesn't care what people think and once she likes something she will stick to it.  

We have to say though, if we looked that good when we hit our 50s, we won't complain!
