Find your fit

Size guide.

Our tees are cut boxy and relaxed. The easiest way to nail your size is to measure a T-shirt you already own and match it to the chart below. All measurements are in inches.

Grab your favourite tee

Pick a T-shirt you already love the fit of, and lay it flat on a table.

Measure the chest

Measure straight across, armpit to armpit, then double it for the full chest width.

Size up for oversized

If your regular-fit tee measures 43 inches at the chest, choose our 45-inch size for a relaxed, oversized look.

Still between sizes?

When in doubt, size down for a classic fit or stay true for oversized. We’re happy to help you decide.
