Adjusting the collar of a shirt
You already own a LE CHEMISEUR® shirt and want to adjust the collar ? This page is for you.
Wash your shirt 2–3 times before deciding on adjustments, or simply keep an extra + 1 cm. Our AI already compensates for the natural shrinkage of each fabric.
Hold the collar closed as you would like it and measure the gap between the centre of the button and the end of the buttonhole with a ruler—add that amount.
If it gapes only slightly, subtract – 1 cm. If you can pinch fabric on the side when the collar is closed, subtract – 2 to 3 cm. Don’t over-tighten: the shirt may become uncomfortable after a few hours, especially in warm weather.
