This is a long-sleeved Basque shirt from Armor Lux. It's made of a medium-weight, smooth fabric. The marked size is 1, which is approximately S-M. Actual measurements are (laid flat): shoulder width approx. 45cm, chest approx. 43cm, length approx. 61cm. Please allow for some slight variations. It has been washed once, so I don't think it will shrink much. It's in excellent condition, having been worn only once. I'm selling it because the size didn't fit. I bought it thinking it was made in France, but there was no indication of the country of origin. Shirt type... Basque shirt Sleeve length... Long sleeve Pattern/Design... Border Neck...
