I'm most comfortable in either a button down shirt (oxford, pinpoint or broadcloth) and either cotton khakis or wool dress pants which are flat fronted with cuffs and creased. If I want to maintain this sort of outfit for a week or two, is there a washable (in sink) dress shirt that can be hung up to dry and khakis which are significantly wrinkle resistant? I would also bring along a travel blazer and several ties.
