J. Crew's new Indigo Deck Jacket is perfect to go with your nautical look and a pair of khaki's. It has a denim look to it so if you are weary of the denim-on-denim look then this isn't an option. I could care less about the denim-on-denim rule because in fashion there are no rules and that's the rule I go by. Made of French Terry Fleece. Available now @ JCrew.com for $138.
