Oasis defined a distinct look in the 1990s that fused working-class style with mod influences, meaning their fashion choices quickly became as iconic as their music. Central to their image was statement outerwear, especially parkas by brands such as Barbour and Stone Island, worn zipped up and buttoned. Along with frontman Liam Gallagher’s lolloping walk, their look became visual hallmarks of Mancunian swagger and remain a symbol of Britpop fashion.

Alongside this, the band loved a lightweight anorak or cagoule, often in shiny nylon, as well as Italian sports-luxe brands like CP Company, which added a football-terrace edge to their look. Noel Gallagher – the band’s primary songwriter and lead guitarist – later coined the phrase “parka monkeys” to disparage his own audience, whom he felt underappreciative of his more experimental solo material, impatient as they were for him to get back to playing the Oasis stuff.

Under the big coats, the Gallaghers’ tops leaned casual and classic: buttoned-up polo shirts from brands including Fred Perry and Lacoste; slouchy crew-neck sweatshirts and retro sportswear from adidas Originals were staples. These pieces reflected both a laddish confidence and a clear nod to football culture. “Their style didn’t reference working-class culture, it came directly from it,” says Andrew Groves, professor of fashion design at the University of Westminster. “The Stone Island parkas, the Umbro training tops, the adidas trainers, none of it was costume. Even their defiance felt lived. That’s why it worked.

“If [rival band] Blur were art school, Oasis were reform school,” Groves continues. “Blur performed ironic detachment, a kind of aesthetic self-protection that kept everything at arm’s length. It was a pop-cultural trick, never fully committing, always framing identity as pastiche. Oasis refused that. There was no irony in their delivery, no distance in how they presented themselves. What they projected, both musically and visually, was conviction.”

“Imagine if they hadn’t had any of that,” agrees Richard Benson, who was editor of The Face in the 1990s, the independent British style magazine that put Oasis on the cover more than once. “It’s hard to imagine them having the influence they did if they were all dressed like, say, Ride.”

“Their great strength was the capturing of the glorious in-the-moment-ness you feel at the best moments in life,” Benson says. “Their lyrics were mostly terrible, but not many people can write and sing ‘You and I are gonna live forever’ and sound like they mean it. Their best looks felt suited to that – street stuff – but really good, comfortable street stuff that you could have the best of times in.”

“Far as I’m concerned, you can write the best record in the world, but if you look like a dickhead, you might as well stick that tune up your arse,” Liam reflected, recently. “You know what I mean? Whereas, if you write good tunes and you look cool – then that’s heaven.”

Footwear was another crucial detail. Clarks Originals – especially Wallabees and Desert Boots – featured heavily, alongside classic adidas sneakers like Gazelles and Sambas, grounding the band’s look in casual Northern cool.

Accessories further defined their visual signature. Liam’s bucket hat is instantly recognisable, as are the round or tinted sunglasses they often wore. Hair played a crucial role, too – mop-top, Beatles-inspired cuts and exaggerated sideburns contributed to a style that was retro, but never costume.

“Liam was just really annoyingly good-looking and one of those people who looked good in almost anything,” Benson says. “I went to Liam and [then girlfriend] Patsy’s [Kensit] house at 10.00am one Saturday and he had just got up and was sitting around the table watching TV with [his mum] Peggy [Gallagher] and Patsy. He was just wearing a T-shirt and track pants, but still looked like he had just walked off stage. Later that day, he was wearing that big white jumper of Patsy’s, the one he wore on stage at Knebworth, in the kitchen, and still looked cool.”

Dressing like Oasis was easy because their style was built on simple, affordable pieces – parkas, jeans, polo shirts and sneakers – that were widely available and already part of many men’s wardrobes. Because their look had a clear identity rooted in music, football and mod culture, it made it instantly recognisable and easy to replicate. It suited most people; they didn’t wear exclusive designer gear or “scary’” fashion. It didn’t require much effort. And it carried a natural nonchalance that made it feel authentic and cool.

“They’re easy pieces to incorporate into your wardrobe,” says the stylist Catherine Hayward. “All you need is a parka, and some suede shoes and suddenly you’re part of the zeitgeist.”

As this summer’s Britpop revival enters full swing, luxury brands also seem to have taken note. See Gucci’s recent flirtation with terrace wear, Wales Bonner’s elevated track tops and Martine Rose’s twisting of lad tropes to incorporate football jerseys and pub-inspired attire into her collections.

“You could argue that much of the recent wave of menswear trends – normcore, Gorpcore, blokecore – can be traced back to the 1990s and ‘Gallacore,’” Groves says. “While fashion has spent the last few years trapped in irony, with brands like Balenciaga turning garments into hyper-stylised, emotionally distant meme content, Gallacore offers something different. It’s direct, grounded and worn with intent. It’s a refusal to perform fashion on anyone else’s terms.”

“I’m me in the supermarket,” Liam once explained. “The same clothes, the same haircut, the same shades on, when I’m fucking gardening or picking the kids up from school or dropping ’em off. I’m the same, there’s no double life. I am what I am.”

Our Legacy offers clean, looser, straight-leg jeans that sit well without screaming retro. Wales Bonner has track tops with sharp detailing that feels fresh, not fancy dress. Needles, too. Look to Sunspel or Beams Plus for knits and polos that are easy to layer. Meanwhile, for the all-important footwear, the recent Clarks x Moncler Genius Wallabee fits the bill nicely. “It’s all about ease, confidence and not looking like you’ve overthought it,” Groves says.

“One thing that Liam has that must be ultra-rare in the style legacy is ‘a walk,’” Benson says, referring to the singer’s rhythmic hip sway and shoulder slouch, easy shorthand for Oasis impersonators everywhere. “The walk was a bit put on in public… but not entirely.”

“My style hero is my dad,” says Lennon Gallagher, the model, musician and son of Liam and Patsy. “I’ve got a few bits from my mum and dad that they don’t know are missing. I won’t say exactly what they are because they’ll want them back.”

Meanwhile, dad’s strong views on style have made themselves known at home. “Even today my dad will be, like, ‘Why are you wearing that? What’s that?’” Gallagher Junior says. “And then I’ll know, ‘OK, don’t wear that around Dad anymore.’”

This summer is set to see a cross-generational champagne supernova of Oasis fans old and new donning vintage track tops, baggy jeans and mod-influenced staples over more aspirational Bond Street names.

That’s not to say the brand doesn’t have close ties to the big luxury brands – Liam has already fronted Stone Island’s AW24 campaign and Burberry’s newly released ‘Festival’ campaign to coincide with the reunion tour. He’s joined in the photoshoot by his Gen Z offspring, Molly, Gene and Lennon (who has previously modelled for the British fashion house), who will no doubt wield plenty of sartorial clout over the younger fans. So, will you too be dressing like a Mancunian rock’n’roll star this summer? Definitely, maybe…
