Hey guys, I'm only 18 now and haven't had the need to wear more formal clothes, so I need some help and advice. Â I will be starting internships in a year or so, and will probabily need to look presentable. Â I'm not sure what the difference is between a sport coat or blazer, if there even is a difference. Â I know that suits are the most formal out of the three, but I also think that they look the best. Â For some reason, I just think that a blazer/different color trousers looks mismatched, and if I was to pair a dark blazer with khaki pants, I think it would look too preppy. Â Anyways, any suggestions for good combinations of colors as far as blazers? Â And which suit styles/colors are good starters? Â I have two pieces which I purchased recently, (if you have the recent Sak's Men's catalog, the ones that I have are the Burberry suit on page 11, and the Canali coat on 8th page of the insert). Â These are a taupe (hard to describe the color, kind of a solid mix of tan and olive) Burberry 2-button single breasted suit, and a Canali 2-button SB jacket in a tan and blue micro-check pattern (almost a houndstooth, and from a distance it looks dark gray). Â Any suggestions would be great.
