I've got a thing tonight, and was wondering about something. I got two suits, a navy 3-button and a dark gray 2-button. The navy is not here right now its in my closet at home (I am at school). I dont want to go with a full suit tonight, but was wondering if I could wear the gray jacket with jeans and a nice shirt. I also have a corduroy jacket but its not as dressy obviously. Would this work or should I forgo a jacket all together for a sweater? Ive heard that a suit jacket alone is not a great idea, unless its navy. Thanks.
