I ever heared a sentence :if you can't lead the fashion trends,you must follow the fashion trends.
What is fashion I think this is a complicatied question.It not only contains clothes\shoes but the most important one,the attitude.Dressing hot or gracely ,pursuing a happy life and something like these are all fashion attitude.
He will fall behind a lot if someone dosen't follow the fashion.And he wil be the one who is always being laughted
at,not because of his dressing but his behavior and attitude.
In a word,I goes for the fashion trends,if i can't lead the fashion trends.
