H5 Lab began, in some ways, with being chronically online. Before it became a pop-up concept store in Dubai offering archival designer clothing and lifestyle pieces, it was a visual fixation: a teenage fascination with Japanese fashion that started online and stayed with its founder, Mustafa Al Hammad. Today, the store centers premium Japanese designers, “specifically Issey Miyake, Comme des Garçons, Yohji Yamamoto being the main pillars of the selection” while also making space for other labels that share a similar sensibility.

Al Hammad, a Saudi creative who spent his formative years in Australia, traces that early attraction back to adolescence. “I’m a Tumblr kid,” he laughs, recalling how Japanese fashion campaigns drew him in almost instinctually. Living in Adelaide, far from any retail spaces that stocked the brands he admired, meant his relationship to them was initially built through imagery alone. As she scrolled through campaign images and archive shows, he found something unexpectedly familiar. “As an Arab kid, without many Arabs around me at the time, I found something comforting in Japanese fashion and culture. There was humility and modesty in it; it wasn’t necessarily as revealing as Western fashion.”But toward the end of his time in Australia, that interest deepened when he discovered secondhand archival stores that became his favorite shops in the city. “I was drawn to the uniqueness of the items that you find in these shops and the experience of you digging through a pile of clothes to find something that resonates with you. It's a special experience that traditional retail doesn't offer so much,” he recalls. Those early spaces also offered something beyond commerce. They were “community spaces,” he says, places open to teaching people who were curious but perhaps unfamiliar with this side of fashion. That ethos stayed with him. After moving to Dubai and spending several years working across fashion retail – from sales assistant to fashion buyer – he began to understand both the possibilities and limits of conventional retail.

Looking back on the traditional retail cycle, he describes an industry constantly producing, discounting, and discarding. “We’re pumping so much product,” he says, much of which is eventually marked down to sales and treated as failure, even when the item itself remains compelling. “That’s actually a very cool, beautiful product, but it’s not necessarily gone to the right hands.” H5 Lab emerged as an answer to that flaw. As a pop-up concept store, “I can control both the operations and then bigger picture-wise, I don't feel like I'm contributing to this, void of infinite products that are always getting made.”Still, launching the concept in Dubai came with uncertainty. Vintage, he notes, had often been associated with more recognisable luxury signifiers, like big-brand logos. When he was preparing for his first pop-up, he remembers looking at the archival pieces he had sourced and invested in thinking: “Oh no, what am I doing. I spent all this money on all this stuff, but I haven't even seen people do vintage here before.”

That audience, he has found, tends to come from the arts world: artists, curators, gallerists, and others drawn to fashion less for logos than for form, history, and point of view. That makes Alserkal Avenue, where H5 Lab has staged its many pop-ups, a fitting base. In a city still shaping its cultural identity, H5 Lab feels part of a wider shift – one that makes room for slower, more considered ways of dressing, collecting, and consuming.
