Shoot, I might be running out of thumbs up with all these feedbacks.
@Claghorn - show me some nice tweeds, I just might. I am gonna lurk around and see who had some great looks with striped shirts.
The pencil striped shirt you got you can just treat as a solid light blue. The shirt where the stripes are a bit farther apart, you'll want to stick with solids or maybe neats. But both are pretty conservative and easy to work with.
