Sleeve Length...Long sleeve Skirt Length...Knee length The embroidery on the collar and skirt is a lovely design. I've only worn it for graduation and entrance ceremonies, so it's in good condition. It's a sleeveless dress underneath, so you can wear it all year round for ceremonies, recitals, etc. I think it would be good to wear a blouse underneath in the fall and winter. How about it for an older sister or younger sister accompanying a Shichi-Go-San celebration? Dry cleaned.
