You can try to change your hair style gar. Because my case is same as you gar...fat face and round...i also worry that wave hair is not suitable for me...but at last i try to change my stright hair into wave style.
Result is.........oh......that's quite good woh...my friends also feel that my new style is better than the old one...shine D... happy D.... Thus, i strongly recommend that you can try try gar...
Don't worry la...wavy hair will make you slim D gar if starting wavy from the ear level, because the face will become longer dd gar (from the visual angle)...i made "陶瓷電髮"gar..quite good gar..you can try this gar..
