The Split Sleeve Shirt Blouse by Irenisa is woven from Brazilian raw silk and fine linen in a plain weave, produced in Ishikawa and dyed in Nishijin, Kyoto. The fabric falls with a supple drape while retaining the understated texture of linen. Full-length sleeve slits extend from shoulder to cuff, their buttoned construction allowing the opening to be adjusted and the silhouette to shift with each styling.
