Try a solid (light) blue, solid white, or blue and white striped oxford cloth button down. Try Brooks Brothers for the classic, or Lands End for something cheaper. Just make sure to buy something that fits. And no non-iron junk.
You won't get much love for those chinos around here, but paired with a button down, a sweater, and some nice shoes, assuming everything fits, youll be better dressed than most people, so cheers to that.
Agreed. You can actually be quite creative with chinos but its advisable to go with better ones, eg Ralph Lauren or even Brooks Brothers on sale, etc
