Size Guide


Our tees are printed on AS Colour Staple 5001 — a midweight (5.3 oz / 180 gsm), pre-shrunk, regular-fit blank with ribbed collar and double-stitched sleeves. Measurements below come straight from the blank maker. Note: all dimensions are taken with the garment laid flat.

How to measure yourself

  1. Find a tee you love. Lay it flat and smooth out wrinkles. Use it as your reference — comparing flat garment to flat garment is always more accurate than body-to-garment.
  2. Measure width. From the seam under one armpit straight across to the seam under the other armpit. That's the body width.
  3. Measure length. From the highest point of the shoulder (where it meets the neck) straight down to the bottom hem.
  4. Compare. Match those numbers to the table above. If you're between sizes, our tees are regular fit and pre-shrunk — going up one gives a relaxed look, staying true gives classic fit.

A note on fit

AS Colour Staple 5001 is midweight (5.3 oz / 180 gsm), built to hold shape wash after wash. Not a slim fit, not a boxy oversize — it's the classic American cut that works under a blazer or on its own. We start our range at M because the design deserves space to breathe.
