Isaia Blue Cotton Shirt

The measurements shown refer to body dimensions, not to the measurements of the finished garment. Handcrafted production tolerances may vary by up to ±1 cm.

Please note: sizes in inches refer only to the anatomical neck circumference. Since the fit of classic shirts follows the lines of Italian tailoring, we recommend checking your chest measurement before you buy. If your chest is close to the upper limit of the range, we suggest ordering one size up.

Measure the sleeve length from the tip of the shoulder (humerus) along the outside of the slightly bent arm to the wrist bone.

This table is not based on standardised industrial grading: it is the result of an advanced anthropometric study based on the real shapes of the human body and on the canons of classic Italian tailoring, and should be read as a calibrated map of the human body. Please refer to your real body measurements (taken against the skin) to find the size that perfectly respects your proportions. Since neck and chest tolerances vary between brands and models, please contact our customer care for a personalised check of your measurements before you confirm your order.
