You are only slightly fat and have a slightly rounded face.
I don't advise you to trim Bobo's head, it will make you fat. I'm speechless. People always recommend BOBO.
Long hair is more suitable for you than grooming. Need oblique bangs, natural broken hair, a little broken hair tail, it will look elegant.
Communicating with the barber and fixing the bangs can make the face look thinner.
In addition, I want to say, pay attention to keep fit, and how girls keep fit and lose weight. You can go to relevant websites or forums for consultation.
For the sake of beauty, pay more attention and wish you good luck.
