I hadn't thought of JCrew--their non-sale prices are crazy, but I might check their sale/clearance stuff. I used to love their shirts back in the early '90s (I still have some that I sleep in or use for home workouts), but I haven't shopped there in many years.

An aside--I seriously miss the days when loose, flowing clothing was in style for people under age 70 or so! If I could dress the way I want with no thought to aging myself, I'd absolutely embrace that style. SO comfortable.
