Thank you all so much for your feedback and suggestions! I should have stated in my original post that my husband and I are only taking a carry on bag each (on wheels.) He'll have a daypack and I'll have a sturdy cross-body bag with a strap too thick to cut. We will both be wearing our Rick Steves money belts.
I appreciate your suggestions regarding leaving the trench coat at home. Since we will be in Amsterdam and Bayeux before we join our tour in Paris I thought it was practical - I will look at Accuweather before we leave and make a decision then. In the meantime I will look for something more packable. The J. Jill pencil skirt is made of ponte knit that stretches and is so comfortable that I own six of them - I wear them year round, even when playing golf - that's actually how I found them. When I reached my fifties I had a difficult time finding a golf skirt that wasn't mid-thigh so I tried one of these last year and rolled the waist band inward. It took two inches off the length to a dignified above knee length - perfect for me! My husband likes the red so much he wants me to take it to Europe - I'd have to really think about that one.
I will be wearing the leggings and tunic sweatshirt (it is french terry, not fleece) on the plane. I may pack a second pair of leggings since these will also double as pj bottoms. As suggested, I will add another long sleeved shirt, long sleeved t, perhaps a lightweight cardi in another color, gloves, knit hat, swimsuit and flip flops. It's great to hear that the Eileen Fischer crepe pants wash and dry so beautifully - glad I made the investment. I will rethink the vests and perhaps leave the denim one home and take my denim jacket instead. I intend on doing laundry at least once, probably twice. For the reader who commented on toiletries: thank you for the tip on the bar soap and shampoo! Hubby can carry the bar soap - Dove is all we use. I intend to take a few small bottles of shampoo/conditioner and then buy just enough for our stay when we get to Paris. The Clinique staff at Macy's here is terrific and I intend to ask them for a few small traveling jars for moisturizer, foundation, etc.
Again, thank you ladies for your helpful suggestions and comments. I don't think I've ever looked so forward to "playing with my suitcase." I hope this thread helps others seeking information on packing light. Best, Liz
