That linen psychedelic Ashland/Keystone shirt that just dropped seems to be in that vein. Have handled in store -- fabric's amazing (runs a hair big I think). Definitely considering with the 15% off coupon from the special order Doyle.
Tough to tell with the small pic, but that looks like a classic white shirt/khaki trousers pairing. Would balance it out with a belt, though, and an interesting jacket of some kind (esp a patterned one). Without something added it looks a bit plain jane to me.
