Is fat face suitable for eight-character bangs?

I don't think it's appropriate. A fat face should generally be suitable for hairstyles that can modify the face. If it looks like a figure of eight, it will be in a state of being put out, and the whole part of the face will be exposed and look bigger. So it is suitable to leave a gradual long edge to cover your cheeks. If you can cover your face, it will make it look much smaller. Of course, proper use of hair dryer is also necessary.
