This is a VINTAGE Japanese Uchikake. Uchikake are trailing kimono that are meant to be worn as overcoats, over top of one's kimono. This piece appears to have been modified for use on stage, and as such, was likely used as a hikizuri; a trailing kimono meant to be worn for traditional Japanese dance. This uchikake appears to have had it's sleeves shortened as part of this modification. Some fabric from the sleeves also appears to have been used to lengthen the garment. There is a little loop sewn into the lining at the back, beneath the collar as well. I believe this was probably used to help hold the collar in place while dressing / dancing.
I have inspected this uchikake in detail, and unfortunately, there is a great deal of discolouration on the exterior. I would rate this uchikake in fair to average vintage condition. It would likely be suitable for some sort of remake, or perhaps it could be used for dance practice (for those learning to dance in hikizuri), or even for an oiran / tayuu cosplay.
205cm - Long (Collar to Hem)
128cm - Arm span
64cm - Width across the back
145cm - Total width of skirt
41cm - Sleeve drop
If you are unsure of how to interpret the kimono's size it is important to know that the length (collar - hem) should be approximately 10cm longer to 10cm shorter than the wearer's overall height (longer is better). This is because the excess length will be folded up at the waist. Meanwhile, the skirt should wrap around the hips a full 1.5 times. The armspan should also reach wrist to wrist on the wearer. If this kimono is worn hikizuri style with the hem trailing, the garment should be equal to the wearer's height or up to 30cm longer. So in that case it would ideally fit a woman who is approximately 205cm (6'9") to 175cm tall (5'9"), with hips about 97cm (38") around. There is some give and take in these measurements though.This piece is currently up for sale in my Etsy shop: www.etsy.com/listing/226035140…
