Thank you for viewing. This is a thin jacket from Mackintosh London. It has stretch and is lightweight, so I think you can wear it without stress. The color is a grayish navy (not dark navy). It has 7/10 sleeves with slits, so you can also wear it folded up. I outgrew it after wearing it a few times. It can be washed at home, which is also a recommended point. It can be worn without ironing. Material Nylon 87% Polyurethane 13% Season Spring, Summer, Autumn Size Shoulder width: Approximately 38cm Body width: Approximately 42cm Sleeve length: Approximately 48cm Length: Approximately 50cm Please be sure to check the profile before purchasing.
