Disclaimer: I'm not a parent, but I was bullied at your son's age and went through the normal headaches of adolescence.

 

There's nothing wrong with encouraging your kid to look presentable around his peers. My advice is don't force him into any particular style, give him options and let him wear what he likes. In my opinion, t-shirts and jeans have never and will never go out of style. Just walk into any department store at the mall and look at what's on the mannequin, you'll get an idea of what's trendy these days.

 

As far as the bullying is concerned, I cannot stress enough the importance of finding an activity that'll build your kid's confidence. Sports can do wonders, just be encouraging. I notice that the kids I work with who are passionate about their activities handle themselves well at school.
