Alas! I have mastered the art of doing the Ashley smile.
I never looked good smiling with my teeth. It puffs my up my whole face thus making it seemed more bigger in picture. The trick to a slimmer looking face aside from the high angle of where the camera is shooting you from is smiling to plump up your cheeks hence making you chin and face as a whole seem more long and thin.
TRY IT ;)
And here’s the person behind the Ashley signature smile.
