How to choose your size?
Take a t-shirt that fits you perfectly, lay it flat, and measure:
- Width (A): from armpit to armpit;
- Length (B): from the highest point of the collar to the bottom hem.
Compare your measurements with the tables above to find the ideal fit.

The measurements provided are taken from the garment laid flat and may have a slight variation of about 1–2 cm, due to normal manufacturing tolerances.

If you have any doubts, we always recommend the larger size, as cotton tends to shrink in the wash!
