Every time I confuse Utsuho and her daughter by Reimu and a chibi Utsuho. Now it's even hard to differentiate them.

Utsuho has a characteristic hair style, the front end divides towards both sides.

Okuu's hair curves out and upward from the middle. Her hairstyle actually has a name. It's called "feathered hair".
