I think it's the kind of girl who cuts her hair short and looks thinner. Girls who are originally thin are not suitable for long hair, because long hair will look shorter. Thin girls with short hair will look taller and the whole person will look smart. In fact, there are many girls in the entertainment circle who look thinner with short hair. Like Zhou Dongyu, for example, Zhou Dongyu had long hair when she first made her debut. Although good-looking, it didn't leave a deep impression on people, because there are too many good-looking people in the entertainment circle, and Zhou Dongyu seems a bit bland.
Later, Zhou Dongyu changed his style and cut his long hair short. She looks like a ghost horse essence and has a special personal temperament. Zhou Dongyu, who has short hair, has always maintained the image of a girl. When Zhou Dongyu is mentioned now, many people may immediately think of her trademark short hair.
Thin Guo Caijie is also suitable for short hair. In fact, Guo Caijie also had long hair, but those long hair didn't leave a deep impression on people like Zhou Dongyu. Later, when she cut her hair short, the temperament of the whole person changed, just like Gu Li in Tiny Times, she was as smart and capable as her facial features were exquisite. Another similar example is Olivia, who wears short hair to be more elegant.
The above examples are all examples of thin girls whose temperament suddenly gets better after short hair, so I think girls with thin bodies are suitable for short hair.
