There’s an unspoken rule in fashion and fandom now: if BTS wears it, it sells out,and it’s not up for debate. The latest proof? RM’s $490 Martine Rose Loafer Mules, featured in his “Butter” concept clip, are now completely sold out in all sizes on the official Martine Rose website and it hasn’t even been a full day since the clip dropped.
The concept clips for “Butter,” BTS’ summer anthem, were released ahead of the official launch on May 21, 2021, and RM’s clip, which came alongside Jungkook’s, showed him exuding calm charisma and chic confidence. One particular item stood out: the sleek, contemporary black Martine Rose loafer mules, which the camera zoomed in and out on several times, almost teasing fans and yes, ARMY caught the details within minutes.
Retailing at $490, these mules weren’t exactly your everyday impulse buy, yet the “Namjoon Effect” proved once again to be an economic force. Fans around the globe rushed to identify and purchase the shoes, and within less than 20 hours, they were completely sold out.
This isn’t the first time RM’s influence has turned a simple item into a worldwide phenomenon. A mirror gym selfie posted by RM once caused a phone case to trend and sell out, prompting the company to publicly acknowledge the massive spike in interest due to “RM’s use.” From books, art, furniture, jewelry, to now designer footwear if RM is spotted with it, even briefly, consider it a collector’s item.
Known for his effortless style, RM has always had a foot firmly planted in both luxury fashion and underground brands, and Martine Rose a British designer known for blending traditional tailoring with edgy modern silhouettes fits his aesthetic like a glove (or, in this case, a mule). RM’s choice of the loafer mules also perfectly matches the “Butter” concept vibe: smooth, cool, and oozing understated sophistication.
The “Butter” concept clips so far have shown each member immersed in a personal moment RM’s was a subtle yet magnetic display of fashion and charm, highlighted by his statement footwear. It’s no surprise that once fans got a closer look at what he was wearing, it turned into fashion gold overnight.
BTS’ Midas touch on everything that comes within inches of their aura is widely know and can no longer be debated, ignored, argued or assumed. A mention, touch, glance, attribution to or even the said item appearance in BTS’ vicinity causes worldwide shortage and panic at the lack of said product. BTS’ RM took a mirror selfie at a gym, and the phone case that was covering his phone became a hot item and even the company acknowledged that more people are interested in that particular product since RM was seen with it.
So, what’s next? Perhaps fans should start pre-ordering anything RM breathes near, because once it enters his orbit, it’s bound to disappear from shelves instantly. Whether he’s on stage, in the studio, or just walking across the frame Kim Namjoon doesn’t just wear fashion; he moves the fashion economy.
ARMY, take a bow. The power you wield paired with BTS’ legendary influence is truly unmatched.
