JILL STUART dress purchased at Kyoto Fujii Daimaru. It's knee-length, but it becomes slightly shorter (1.2cm) when a petticoat is worn. I wore it once for a wedding. The neckline is in the shape of a collar, like a little devil, and it's cute. The fabric is thick and sturdy, so it can be worn year-round. The elastic in the petticoat might be stretched out.
