This is a vintage han juban top that is meant to wear under a Japanese kimono. Made of cotton with pink and blue floral print sleeves. It is not lined, no ties or belts. Hangs open in front. Very good condition apart from a little yellowing on the back of the left shoulder, see last photo.

Hand made in the 60s to 80s. No tags. No stretch. Refer to measurements and leave room for ease of movement. 

Around the body, measured across the back and doubled - 48 inches
Length - 21 inches

Hand wash or dry clean. Possibly on gentle cycle in cold water, but I would not recommend it.
