Chest: measure across the fullest part, under the arms, and double it. Length: from the highest point of the shoulder straight down to the hem. Compare to a shirt you already own and love.
Fit notes
- Tees & long-sleeves: classic unisex cut, true to size. Size up for relaxed/oversized.
- Women's fitted tee: cut closer to the body — size up if you prefer a looser fit.
- Hoodies & crewnecks: roomy, built to layer over a tee.
- Everything is heavyweight cotton or fleece — no thin, see-through blanks.
