Vintage Alfred Shaheen long sleeve floral dress

Stunning vintage floral hand printed maxi dress by popular Hawaiian designer, Alfred Shaheen. Constructed in a light ivory beige fabric with the exclusive hand printed signed “Shaheen” with a beautiful yellow and orange floral print. Long bell sleeve with print along the arms. Three buttons on the center of the top. There are two tags on the dress, one is Alfred Shaheen with care instructions, the other reads “An exclusive Sig Plach Couturier Edmonton Canada” former designer/shop in Edmonton, Alberta. There are no tags indicating the fabric but the outer layer is lovely and drapey, almost like a linen or cotton, but cannot confirm. The dress is lined. It’s in fantastic vintage condition. Hard to tell if it’s been worn before or if so, it’s been lightly used. Mild musty scent, I’m guessing from storage/its age, I have not attempted to wash. There is no sizing, but the store I purchased from marked as size small. Some measurements in pictures.
