Growing up, I was always stealing my dad’s or my older brother’s shirts. I loved the ease of them, the way they looked better oversized, worn-in, undone. I would see guys around town coming out of work, stopping at the grocery store or gas station, and I always coveted the cool, effortless confidence of those shirts. Perfectly lived-in and impossible to find. 

The ATH Mechanic Shirt was born from that feeling.

Each shirt is very specifically sourced and reworked by Holly in the ATH studio. The original shirt’s authentic wear, softness, and lived-in character are preserved, then finished by hand with a unique mix of ATH details: vintage labels, studs, buttons, paint, artwork, distressing, and hand-applied treatments.

No two are alike. Each piece carries its own history, its own treatment, and its own numbered identity, a custom one-of-one shirt made to be worn and loved over and over again.
