This jacket is made from silk blend yarns. The fabric is hand loomed and pre washed. The irregularities and variations in the texture are characteristic of the garment and should not be considered defective. The outside is irredescent blue; the inside is black. Dry-clean. Can be rolled up and is not wrinkled when unfolded. Customers have told us that jackets size large and have normally bought one size smaller than their usual size.
