Built from a big body, not sized up from a small one.
The Big Boy's Shirt, cut for a big body, is built for confidence with zero effort.
Engineered with our exclusive BigFit™ fabric, an innovative blend of polyester, bamboo fibre and elastane, so it closes flat over the belly and stays tucked all day. A sharp, refined look combined with natural breathability and ultimate stretch comfort.
Upgrade your mornings. Reclaim your time.
Machine wash cold at 30°C on a gentle cycle. Avoid bleach, harsh detergents and fabric softener. Hang to dry naturally. Tumble drying not recommended. Light steam at low temperature can be used if needed.
Tested through 500+ machine cycles, with no loss of shape or body length.
Designed to remain crisp, clean, and elegant wash after wash.

It was never your body, it was the shirt. Every other brand grades a slim pattern up and calls it XXL. Here is what we changed:
Room engineered in at the belly, so the cut holds the front closed and the buttons stay flat when you sit.
Matte fabric, tone-on-tone buttons, no chest pocket. A clean line instead of a potato sack.
Cut longer in the body, so it stays tucked when you reach up, get in the car or sit through a long meeting.
Breathable with a touch of stretch, so you stop planning your day around sweat patches.

Every dayWe could not find one shirt that did all of this at once, so we built it. Here is how it holds up against a luxury shirt and a classic one.
"First shirt that closes flat over my belly and stays tucked. I'd stopped believing it existed."
