I ordered this vest from Overstock, and even though they sent me the wrong color it was a very nice gift for my husband. It can be worn casually over a button down with some jeans, but it can also be worn in the business environment with dress pants and a shirt and tie underneath. Then there's also the use of this vest on the golf course to add another layer. My husband has gotten MANY compliments on this vest, and I'm very glad I purchased this.
