An oval face has slightly wider cheekbones and a gentle narrowing at the forehead and jaw.
if you have oval face shape , then congratulations! You can wear almost every kind of glasses!!! I suggest that you can go with statement pairs, for they are so cute! Why not show the world that I am perfectly satisfied with myself.
A square face has more angular lines with equally wide cheekbones, forehead and jaw.
Then let’s move on to the opposite side. Square face need round glasses. I think that’s something we all know. Sometimes it works, but sometimes it’s just not right. Then we should consider the material and the design.
