Just wear some slim clothes. You can refer to the life clothes of some Korean stars. I am as thin as you. I usually prefer to wear some small suits with a waist, with a white shirt or casual white autumn clothes, black pants and white shoes. If the sun is shining, bring sunglasses. Very temperamental. Besides, bring some jewelry.
Just have long hair or a perm and fluffy hair. It's good. I'm doing it now
Only on behalf of personal views, don't spray if you don't like it, thank you.
