I took measurements with my husband and attached the measurements to the size chart. It said he wears XL as usual, so I ordered 2 shirts in XL. The shirts arrived on the promised day. But they fit like M, not XL - the sides were 3 inches apart. They were also made of thin, spiky "cotton and linen". I didn't see a label in the collar. The washing label says "dry flat, not in the sun". It will probably shrink. Back to my trusted brand: Cubavera.
