   Dear Cathy,    I am writing to share my opinion on fashion with you, for I had just heard that you are disappointing because you can’t afford famous brands.    I shall say that it is natural for people to care about his appearance. And it is true that fashionable thing like clothes and shoes will make one more eye-catching. However, I think it is real a waste of money for you to buy famous brands. Besides, it will also add the burden of your parents.    What’s more, beauty is only skin-deep. There are many other things in which can make you popular beside fashion.
