The packing list I offered Margo at the beginning is what was distilled from my "use-it" theory of packing. I think of all the various activities I expected, then make sure I had an entire set of clothes, coat & shoes that would work for that activity.
The airplane outfit.
The museum and shopping outfit.
The special event outfit.
The hit-the-pubs outfit.
The hiking outfit.
The boating outfit.
The swimming outfit.
The comfy outfit. (This one is the most important for me... the slop around the place, don't even look at me clothes.)
