Pattern Design: Solid color. Collar is removable. Sleeve Length: Short sleeve. Season: Spring, Autumn, Winter. Color: Described as navy, but it's a dark navy. I bought this about two years ago at a department store for around 25,000 yen (^^) I wore it once for a short time to a child's school observation and have kept it in my closet at home. Total length is 96 cm, and the fabric is thick and sturdy. You can wear it in winter if you put on a cardigan or something similar♪ It can be washed at home with delicate wash. The collar is removable, so you can wear it in 2 ways!
