1) I can't say that I spend a lot of money on my clothes. Usually my parents buy me clothes but sometimes I use my pocket money to buy a thing I like, such as a cool T-shirt or a cap.
I used to wear some clothes from my elder sister when I was younger, but now we are the same height, so we both have our own clothes. Sometimes we even borrow clothes from each other.
2) The best fashion advice I have ever been given is to avoid following fashion blindly. It is very important to be yourself and wear clothes that properly fit. For instance, there is a trend of wearing ripped jeans. People buy them to look “cool” but the thing is that it doesn't matter what you wear — the thing that matters is it should look good on you.
