James Collier

Founder & Lead Clothier
A native New Orleanian with over a decade of experience in menswear, James leads Kilby’s tailoring and client services. He’s particularly passionate about a garment’s fit and proportions.

His approach combines traditional craft with a relaxed, Southern sensibility and a philosophy shaped by years of fitting clients ranging from business leaders to professional athletes, including Drew Brees, Eli Manning, Daniel Cormier, Jayden Daniels, Will Campbell, T-Bob Hebert, and Dylan Crews.

Whether designing a formal dinner jacket or a relaxed safari coat, James’s goal is always the same: to create clothing that feels personal and effortless.
