Size Guide
Every KYSM tee is the AS Colour Staple 5001 in a regular fit — straight body, set-in sleeves, hem just below the hip bone. Not oversized, not boxy, not cropped.
MEASUREMENTS
These are measurements of the garment laid flat, not of your body. Chest width is measured across the front from one underarm seam to the other.
| Size | Chest width | Body length |
|---|---|---|
| S | 47 cm · 18.5 in | 71 cm · 28 in |
| M | 52 cm · 20.5 in | 75 cm · 29.5 in |
| L | 56.5 cm · 22.25 in | 78.5 cm · 31 in |
| XL | 61 cm · 24 in | 82 cm · 32.25 in |
| 2XL | 64 cm · 25.25 in | 83.5 cm · 33 in |
| 3XL | 68 cm · 26.75 in | 85 cm · 33.5 in |
| 4XL | 75 cm · 29.5 in | 87 cm · 34.25 in |
| 5XL | 80 cm · 31.5 in | 89 cm · 35 in |
AS Colour's stated tolerance is 2.5 cm, so treat these as close rather than exact.
THE ONLY METHOD THAT ACTUALLY WORKS
Forget your usual size. Brands disagree with each other and always have. Instead:
- Find a t-shirt you already own that fits the way you want this one to fit.
- Lay it flat on a table, front up, and smooth out the wrinkles.
- Chest width — measure straight across from one underarm seam to the other. Across, not around.
- Body length — measure from the highest point of the shoulder, right beside the collar, straight down to the hem.
- Find the closest match in the table above. That's your size.
Two minutes, and it beats guessing every time.
IF YOU'RE BETWEEN SIZES
Size up. The Staple is preshrunk so it won't grow, and a tee that's slightly roomy reads as a choice while one that's slightly tight reads as a mistake.
Want the oversized look? Go up one full size. These photos are shot on a regular fit, so what you see is what arrives — sizing up is a deliberate decision, not a correction.
For reference, AS Colour's own fit model is 183 cm and wears a Large.
LOOKING AFTER IT
Machine wash cold with like colours. Don't bleach. Don't tumble dry. Don't iron the print. Line dry in the shade.
Preshrunk, so shrinkage is minimal — but heat is what kills a printed tee. Cold wash and a line in the shade and it'll outlast most of your wardrobe.
