That at 22, justin bieber clothes is the middle of polemic debates about his style can be something of your surprise. He’s not revealing giant swaths of skin, donning outrageous meat-covered coats, as well as flaunting particularly controversial slogans across his shirts. Instead, they have a penchant for tees that nearly scrape his knees, exaggerated layering, and skater boy clothes — not quite tabloid fodder.

Yet even so, he’s drawn considerable attention (and backlash) for more recent looks, much like the Nirvana band T-shirt by L.A. brand The fear of God which he wore for the American Music Awards late last year. Critics were scathing: the reigning prince of pop dares to be associated with the storied grunge band?

Longtime stylist Karla Welch, who first signed on to do business with Bieber on his Believe Tour in 2012, has a explanation for all the hoopla: It’s a testament to the singer’s growing style influence. “He’s been pushing men’s fashion for the last five years,” she says. “Should you look at the start of the Believe Tour, he was getting heat for your drop-crotch pants and super long T-shirts. However right now, if you get to any menswear store, you can see those styles reflected.” Similar to Bieber, Welch doesn’t “worry about negative feedback,” she says. “Haters gonna hate.”

Despite the Nirvana controversy, Welch went to The fear of God and worked with the designer Jerry Lorenzo on five searches for Bieber’s current Purpose Tour, which kicked off Wednesday night (March 9) in Seattle. “We have been buying [Jerry’s] stuff during the last 2 years; it’s been a really fun process working [together],” Welch says in the custom-made denim and tees. Interspersed will likely be Raf Simons pieces (“Justin is very into Raf lately”), Adidas shoes, and justin bieber hoodie, like thigh-skimming T-shirts for layering. “I really could see the looks changing from concert to concert together with the way Justin chooses to style them,” Welch adds.

Though certain technical adjustments happen to be designed to the tour wardrobe, including zippers, gussets and reinforcements for quick changes (they have lower than one minute to improve backstage), the design is not really so distinct from what the singer sports regularly on Instagram. “It’s more street grunge by using a very vintage skater feel,” Welch describes. “I found myself living in Vancouver in the grunge era — I employed to drop to Seattle to watch Pearl Jam play — and I always loved how those stoner boys looked. That’s bieeber we started doing with the Purpose videos and now with all the tour. It’s very undone.” The show’s backup dancers, who channel a similarly relaxed aesthetic, are outfitted in apparel by Calvin Klein, with whom justin bieber t shirt has an ongoing campaign handle.

Raised in Powell River, British Columbia, Canadian heritage has become an asset for Welch from the start. “We just met and clicked,” the stylist says of Bieber, who matured in Stratford, Ontario. “Canadians inherently love Canadians; that’s for ages been a bond. Canadians are super nationalists,” she adds, chuckling. Though Welch is normally tending towards the red-carpet wardrobes of universally adored actresses like Amy Poehler and Olivia Wilde, she says there have been no hesitations about dealing with a more controversial pop star like a client. “When you hear everything the press needs to say, you’re losing at life,” she says, noting that now more than ever the two use a “100 % collaborative” relationship. “Justin enjoys the process.”
