1. Really couple of things are sexier than a guy who understands how to rock a blazer with a cool shirt and jeans. A lot of men can't manage it. They either end up in a semi-formal fit and tie look or plain old denims and a T-shirt. For them, there's no in between. To those men, I would suggest that you try believing about it regards to being "semi-casual". Odds are, you'll end up with something a great deal more trendy.
