"This whole project has been about bringing youth as a creative entity, and bringing young students as the creative entity, to contribute to the philosophy of Izzue-which is about youth, and about movement and a community that needs to buy and wear easy and appealing products," he says.

Sustainability also doesn't need to be a complicated matter, he adds, eyes wide open to the idea of another Izzue x CSM collaboration. "At the end of the day, you want novelty and innovation in materials, and you want an entity like Izzue to choose a material that is not what they use all the time."

So what would Piras propose for a follow-up crossover? "I would go with a range of T-shirts, sweatshirts and something totally visual," he says. "At the end of the day, it needs to be fast. It can be a very simple choice, such as which cottons you use, which nylons you use. You can do something really simple just by using one element that changes everything."

Which sounds a lot like the ideal tagline for Izzue. Today, London; tomorrow, the world, as the brand activates plans to expand its stores beyond its current stable in Asia. Hong Kong's global fashion moment may be at hand at the helm of Izzue and I.T, and we're certain the anti-sentimental, future-driven Mr Lagerfeld would have approved.
