Hello, I'll be moving for NE to Dallas. As you know about 4 months a years it's pretty hot. I will be working in a business casual environment that is conservative. I was considering various fabrics but I think wool would be best. I have been searching various clothing sites and searching the forums but can't seem to find a good "all season wool" or "tropical wool" Blazer. I want to spend max $500. Any suggestions? Thanks a lot in advance!
