Thank you for viewing! m(_ _)m This item was made by deconstructing a kimono, hand washing it with Emal, air drying it, and ironing it before sewing. I purchased it as Oshima Tsumugi, but there is no certification tag m(_ _)m Pure silk! Flat measurements: Length: 97cm Width (armpit to armpit): 67cm Sleeve length (center back to cuff): 68cm Cuff width: 13cm Long sleeves There are no pockets or lining. Alterations are not possible m(_ _)m The collar is designed to look like you're wearing a kimono ^ ^ It has an I-line silhouette, so it looks neat. It's stylish and cool when paired with wide pants, etc. ^ ^ You can wear it year-round except in mid-summer if you change the inner layer. For washing, wash it separately as the color may fade! Hand wash gently with a detergent for delicate clothes. Briefly spin for about a minute, pat it to shape, and air dry ( ^ω^ ) I try to make it carefully, but please understand that I am using a used kimono and that it is the work of an amateur, an old lady m(_ _)m
