Keeley Hawes takes a step back in time in 1940s-inspired vintage green suit as she attends Goodwood Festival before changing into a swimming costume for a cold plunge

Keeley Hawes took a step back in time as she dressed to impress for Goodwood Festival over the weekend. 

The actress, 50, wowed in a 1940s-inspired vintage green tailored blazer jacket and matching skirt. 

The star completed the look with black heels, a stylish black hat and quirky sunglasses. 

Keeley enjoyed the weekend with her makeup artist Justine Jenkins as the pair later slipped into their swimming costumes and dressing gowns for a cold plunge. 

Enjoying plenty of fizz, the star then sat down to enjoy a five-star meal before watching the races. 

Keeley's latest Instagram update comes after she shared some rare snaps with her husband Matthew Macfadyen as they holidayed in Turkey last month. 

The couple enjoyed a stay at the five-star hotel The Peninsula in Istanbul, with the actress, 50, sharing highlights from her trip on Instagram.

In one photo, the couple put on a cosy display as they headed out to sea on a boat trip. 

Keeley looked effortlessly stylish in a white and blue patterned co-ord and kept cool with a baseball cap and sunglasses. 

The Bodyguard star also uploaded a photo of Matthew, 51, as they had a romantic dinner date. 

The couple met on the set of Spooks 24 years ago in 2002.

In November, the pair celebrated 21 years of marriage, with Keeley taking to Instagram with a selection of loved-up snaps, in what became one of her most liked posts, as she penned: '21 years. No notes. Love you with all my heart.'

Speaking to You Magazine, she said: 'It doesn't feel like 21 years, by any means. We just sort of have a nice time. And also, you become more relaxed [as you get older]. 

'It would be weird to have a marriage where things don't go up and down occasionally in 21 years, but we're very happy.' 

Explaining it is the simple things that have resulted in their lasting relationship she said that now their children have left home they make sure to do things together, particularly travelling and spending time with each other. 

Yet their road to happily ever after was by no means smooth sailing, with Matthew previously describing the moment he fell in love with Keeley as 'awful'.   

At the time Keeley, who was then 26, was newly married to DJ Spencer McCallum, with whom she shares 25-year-old son Myles. 

Speaking to The Mail On Sunday in 2005, Matthew confessed he was in turmoil when he first met Keeley as he realised he had feelings for a married woman. 

He explained: 'It was awful because I realised I'd fallen for her. We weren't having an affair and it was a slow process. But I knew the effect she had on me. She's gorgeous. Everyone who meets her will tell you the same thing.'
