I am going on a dinner date this weekend and am relatively new to paying attention to mens fashion. I am a blue collar worker, who outside of my dingy work uniform, have always just been a jeans and t-shirt kind of guy. I'm 37 years old and want to change up my image a bit, and just dress better over all. We are headed to a slightly above average dinner at an Inn on a small lake and I would like to dress well but not overly. I'm a larger framed guy at 6' 210 lbs so finding decent clothes that fit well have always been an issue. and I don't think I want to wear a blazer or sport coat....it just isn't me. I like darker colors. Any suggestions??
