Hello, MFA. I'm new here, and I plan on going shopping for clothes soon.

I'd like advice on what to wear for the winter months, I live in texas so isn't too cold, but I do enjoy lots of flannel and jeans, and my friend says I wear it too much, so I'd like some tips on dressing myself and what clothes would look good on me. I'm 16 years old and I'm about 6'1" and 200 lbs.
