“When I design, it’s my personal vision,” says Gerardo Cavaliere, co-founder of Giuliva Heritage, about his singular aesthetic that’s become one of the hottest menswear brands for top actors right now.

“He’s the muse,” says stylist Warren Alfie Baker, who regularly interprets Cavaliere’s vibe — think Italian neorealism heartthrob meets Dimes Square charm — for his roster of A-listers. For the premiere of Ripley in April, client Andrew Scott looked playfully roguish in an acid green shawl-lapel suit and low-scoop-neck tank, while that same month Diego Boneta smoldered in a Giuliva Heritage ultrawide peak lapel suit and silky shirt with undone buttons.
