Brooks Brothers is having a 40% off sale on these things (and they have my size!), so I'm considering getting one, mainly to wear with my jeans but maybe also trousers/chinos. They also have a wool/cashmere blend version in navy and charcoal. Which color do you guys think will be more versatile? Also, stick with cotton or go with the wool blend? I know that the navy blazer is considered to be a staple, but I don't know if that applies to soft jackets, too. I'm somewhat partial to the charcoal (from the picture it looks like it has a bit more texture than the tan or navy), and my gut tells me to stay away from the tan. I've never really worn tan before other than for pants, and I just don't know how good a tan jacket would look with khakis. But I'm a bit of a newbie with regards to blazers and sport coats and the like; I don't really know how well they pair up.
