This item is quite old.I purchased it from a department store boutique for around ¥19,800.It's very charming and carefully made.It originally had shoulder pads, but they have been removed.Please see the photos of the shoulder area (photo 7).Size 7, but I think it can also fit someone who wears a size 9.Shoulder width: 39cmBody width: 51cmLength: 45cmSleeve length: 53cmThese are approximate measurements. Please understand.How about it for sun protection or to prevent chills from air conditioning?Thank you. Perfect for everyday use. superior materials and excellent craftsmanship ensure long-lasting durability.
