With stylist Dani Michelle on speed dial and an endless closet within reach, Haley Bieber's Coachella attire could have gone in any direction. But when it came time to dress for a weekend of late-night concerts and celebrity shenanigans, Bieber embraced the no-pants trend, a look she just can't stop, in two variations.

First, the Lorde founder attended Revolve Fest, the online retailer's annual concert meets celebrity hangout, on April 13 in an outfit that mixed a few of her favorite coords. Bieber's casual look started sporty in a green Nike soccer jersey, then transformed into a Sofia Coppola look with lace bloomers, Sandy Leanne's Mary Janes, and rolled white socks.

The next day, Bieber opted for heavier layers, at least on the upper half. Instead of light white bloomers and a soccer kit, he changed into a voluminous Balenciaga leather jacket and tough Miu Miu leather boots with lug soles. A black T-shirt peeks out from under the coat's collar. pants" she still doesn't know.

Over the weekend, Bieber clung to Rohde's lip-gloss phone case to watch performances by Ice Spice, Dodger Cat, and others, but she wasn't so glued to her leather jacket. At one point, the Victoria's Secret model changed into a vintage Yankees varsity jacket and paired it with a Phila baseball cap wrapped around a leopard print scarf. The look Bieber shared on her Instagram Stories shows that she also incorporated cargo pants into the look. (Who would be surprised?)

Various celebrities have embraced the no-pants trend in recent months, from Kristen Stewart promoting her movie "Love Lies Bleeding" in hot pants to Dua Lipa walking around London in just a Ferragamo leather jacket. Bieber's best friend, Kendall Jenner, was one of the first to embrace the no-pants trend.

They have plenty of runway backup: designers from Gucci to Miu Miu to Bottega Veneta have incorporated tiny micro shorts into their recent collections. But no celebrity or model is more committed to this look than Hailey Bieber.

While Rihanna's Coachella outfits were maximalist with oversized layers and fur coats, and Taylor Swift's Coachella outfits were her impending Reputation 2.0 era, Haley Bieber's two pants-less looks, may have been the truest reflection of personal style on the festival circuit. Of course, going pantsless is an inevitable trend, but by wearing it everywhere, she proved to be a pillar of her own wardrobe.
