Never mind the posh frocks… Now it’s Phoebe Waller-Rotten!

Whoever would have thought that the impeccably posh Phoebe Waller-Bridge – the descendant of two baronets – would have anything in common with punk star Johnny Rotten?

But it appears that they have very similar taste in fashion, with the Fleabag creator being spotted last week in a black outfit with plenty of zips, similar to the sort that the Sex Pistols frontman wore in his wild 1970s heyday.

It’s likely that Ms Waller-Bridge’s version was a lot more expensive – her all-in-one, called the Bauhaus, was made by Californian fashion designer Rick Owens and is currently available for £1,285.

Zips, along with safety pins and chains, were an essential part of the punk look and Rotten – real name John Lydon – was pictured in a very similar outfit in the 1970s. Clash frontman Joe Strummer also wore a near-identical jacket in photoshoots.

Ms Waller-Bridge wore the outfit as she dined at London celebrity haunt The Ivy with her director partner Martin McDonagh. She teamed her jumpsuit with a pair of burnt orange Adidas Gazelle trainers which cost £100.

But if her look is punk, the 37-year-old star’s musical tastes are a little more mainstream. 

She is a big fan of Harry Styles and has spoken of being inspired by Jennifer Lopez.

Ms Waller-Bridge’s black jumpsuits have attracted attention in the past. 

During the opening episode of the second series of Fleabag, she wore a £50 black halterneck keyhole jumpsuit with wide leg trousers from fashion brand Love, which sold out almost immediately. 

The star, who attended the £13,000-a-year St Augustine’s Priory school in West London, opted for more glamorous attire when she walked the red carpet on Monday night for the London premiere of Indiana Jones And The Dial Of Destiny in a chic chainmail dress.

Harrison Ford was also in attendance to celebrate his final outing as the archaeologist, at the age of 80. 

Ms Waller-Bridge plays his goddaughter Helena Shaw, with Mads Mikkelsen playing villain Jurgen Voller, an ex-Nazi who now works for Nasa, and Toby Jones as Basil Shaw, an ally of Jones.

She has said her journey from Fleabag, which started as a fringe theatre show, to Hollywood blockbuster has been ‘surreal’ but said: ‘There’s room for a slightly clumsier, bruised, limping female action star.’
