Is it bad to dress nicely?

I’m poor, from a middle class family and I like to wear nice clothes. Because of that, all my friends had trouble believing that I liked a rich guy for who he was. Including the rich guy. I use my own money to buy this stuff. Does dressing nicely give people the wrong idea about you often? Does that mean I have to dress like a bag lady?
