This long-sleeved shirt is made from a very intricately-structured dobby weave seersucker fabric, achieved by using the shrinkage difference between cotton and polyester linen threads to create unevenness. The multi-colored threads in both the warp and weft intersect finely, resulting in a plaid pattern with depth that is reminiscent of a deep forest swamp. The pattern of this product varies from item to item. Please note this in advance.
