Damian Lewis’ rock and roll style evolution inspired by his new grunge loving girlfriend Alison Mosshart

He was once a poster boy for traditional and classic Etonian style, donning skinny ties and crisp suits on red carpets around the world.

But A-list actor Damian Lewis has had a rock and roll makeover – and it’s all thanks to his grunge-chic girlfriend.

The Billions star, 53, began dating 45-year-old Alison Mosshart in 2022, a year after his beloved wife Helen McCrory died from breast cancer.

Since dating Florida-born Alison, frontwoman of rock band The Kills, Damian has signaled a break from his sharp and luscious style, opting for more adventurous outfits inspired by his new flame and her signature grunge look.

The pair, who are no strangers to a little PDA, have occasionally matched their outfits, with Damian opting for more casual outfits when out and about – and one style expert reckons his new look is down to Alison encouraging him to ‘taking risks’.

Earlier this week, the pair were snapped out on a date night in London, both dressed in similar stripped down grunge attire.

Alison was pictured wearing a cap, a black hoodie with skinny jeans and a pair of New Balance shoes, paired with chunky gold chains.

The father of two wore a leather jacket paired with a beige hoodie and some charcoal trousers, also wearing New Balance shoes.

The couple even decided to match their outfits for a Vogue World red carpet event last September where they presented a sartorial union.

They both wore sunglasses and posed arm-in-arm for the camera, despite the event being in the evening.

Alison went for a vibrant blush colored suit with a black and gold star print blouse underneath, indicating a playful sense of fashion.

Damian also pushed his boundaries and decided to wear banana colored suit trousers matched with a black shirt and blazer.

Celebrity stylist Rochelle White said: ‘I think Alison has encouraged him to take more risks and be bolder with his style and try new things.

‘She has a natural edge to her style and it could be that he wants to step out with her in a way that compliments her look and style – and not be too suited and dusty.’

Before his relationship with Alison, the musician played it safe, going for patterned shirts, a pair of tailored trousers and polished shoes.

But Rochelle believes his newfound sense of style has shaved years off his looks, adding that he’s trying to tap into a younger sense of fashion.

“He’s comfortable enough to express who he is, take risks and step out of his comfort zone,” she said.

‘He’s been seen as the clean, classic gentleman for a long time and now it’s time to have fun and express who he is through his clothes and looks.

Commenting on his yellow pants ensemble, Rochelle thinks this look shows how relaxed he is around Alison.

“I think that look sums up where they both are in their relationship and where he is in his life,” she said.

‘I feel he looks a bit younger in this outfit and they have a rock’n’roll vibe about them. I feel it takes a really confident person to be able to rock yellow pants and he has achieved that.’

Last April, the pair attended the launch of the Bowie X Mother collaboration in London, where the 53-year-old donned a hipster leather jacket.

He paired it with a David Bowie band t-shirt, a pair of jade colored tailored trousers and some white loafers.

Alison was in her usual monochrome star print jacket, black skinny jeans and boots as she posed with her boyfriend with a cocktail in the other hand.

Once again, the pair showed a sense of togetherness in their relationship through their outfits as Alison wore green nail polish to match Damian’s trousers.

Rochelle said: ‘I think Alison has influenced his overall style. I feel she has shown him a new way to show who he is and his personality through the outfits he wears.

“He was probably a bit too classic for her (before) and obviously with the development of their relationship and public image, (clothing has) played a role.”

His new unique outfits contrast the ensembles he used to wear to red carpet events over the years.

Events from previous years show the actor opting for colors here and there, but generally sticking to more muted tones in his outfits.

He was known to favor tailored suits with ties and always looked sharp – however his new look is somewhat more adventurous than previously seen.

Damian still opts for gray from time to time, but has been experimenting with accessories including paperboy caps, combat boots – or even just a built-in collar to add another element to the overall outfit.

Asked why she thought Damian took inspiration from Alison’s wardrobe, Rochelle said: ‘She’s known for that rocker look both on stage and off. She is not the classic “clean girl” fashionista chick when it comes to her look.

‘Usually she rocks jeans, boots, t-shirts, bold patterns and prints. I feel like he wants to match and compliment her aesthetic, but in his own way.

“His previous look was classic, safe and stylish. I feel like he’s in a place where he can sit back, relax and have fun with his style.’

And fashion isn’t the only thing Alison has influenced, as he also joined Instagram in 2022 – the year they started dating – much to the delight of his fans.

Damian’s first post was him on stage with his guitar, and he often posts videos, stories and snaps of him singing and playing instruments, following the same rock star aesthetic as Alison.

She also has the social media app and their accounts look almost identical, with music being one of their biggest shared passions.

The pair were first seen together in the summer of 2022, with Alison’s mother Vivian giving their relationship her seal of approval.

She told MailOnline: ‘They have mutual friends. I don’t know exactly how they met, but I’m fine with that. If she’s happy, we’re happy.’

This was just over a year after Helen McCrory, Lewis’ wife of around 14 years, had tragically died after a secret battle with breast cancer.

When Helen died in April 2021, Damian revealed how his late wife had urged him to find love again, telling him and their son and daughter that she wanted ‘dad to have lots of girlfriends.’
