Ishigami-san created a traditional long skirt with a grey base and tartan checks, using yellow, which is her current favorite color, as the accent point. By making only the left side a plain mustard yellow, it looks more sophisticated and is easier to match with tops! It has a wrap-around skirt-like feel, so the hem won't flip up, and the elastic from the sides to the back of the waist makes it comfortable to wear, and it's packed with great features.
