Adjusting the sleeve length of a shirt

The correct sleeve length for a shirt

Standing, arms relaxed and with the cuff button open, the sleeve ends about 3 cm above the base of your thumb.

LE CHEMISEUR® tips

🤏 Allow for shrinkage

Wash the shirt 2–3 times before deciding on alterations, or leave an extra 1 cm. LE CHEMISEUR®'s AI compensates for the shrinkage of each fabric.

👔 Wearing your shirt with a jacket

The shirt cuff should extend about 1 cm beyond the jacket sleeve.

📏 Balancing for height

Very tall wearers can add + 1 cm so the arms look less long; shorter wearers often subtract – 1 cm for better proportions.

👕 Special case : short-sleeve shirts

Keep your usual long-sleeve length and, under Personalise › Cuffs, select “Short Sleeves”; we will calculate an optimum fit automatically for your build. You can also enter an exact short-sleeve length here (e.g. 24 cm).

How to measure sleeve length on a shirt

Lay the sleeve flat and measure from the end of the cuff to the seam where it meets the shoulder. French cuffs should be folded, as when worn. Most ready-to-wear shirts have sleeves around 64 cm long.

Tolerance: A difference of ± 1 cm between your measurement and your Fit Key is perfectly normal.
