These kind of topics are always amusing.
While we were doing laundry together, I asked a woman on a RS Best of Scandinavia tour why she had such a large suitcase. Her primary reason was that she couldn't stand to wear anything more than once without washing it. I hadn't heard that one before.
I noticed on my RS tours in June that the people with the largest luggage oddly tended to have a "uniform." They may have changed their shorts or pants or shirts or blouses or tops or shoes regularly, but the articles of clothing were so similar that the changes weren't noticeable. So did they really need multiple versions of the same thing?
The person who had the smallest bag had the most versatile and interesting clothing of anyone. She looked great in everything she wore and I bet she had no more than a total of 7 pieces.
I own neither a skirt nor a dress. I look dumpy in them and showing my legs would scare the kids. So out of vanity and a concern for future generations, I wear pants exclusively. Skirts long enough to cover my legs are invariably heavy and voluminous. Definitely not suited for light packing.
My husband owns no suits. He lives in a blue jeans and T-shirt world. He does have a sport coat and some fairly nice pants. He takes that with him to WA each summer, for the funeral in case another one of his classmates dies while he's there. He has been known to pack more tees than he needs and wear only 1/4 of them. But he never takes more than one pair of shoes.
It seems like a number of comments about the need for packing heavy are related to combining cruises with time on land. I have no experience with that probably never will, even on a river, because he gets seasick, so we'll never have to worry about appropriate clothes for that situation.
I do like to take a 2nd pair of shoes to put on in the evening. I got these and took them on my trip this summer. They fit perfectly when I left Tucson, but just a few days in Lisbon with the very salty food and my feet swole up so much I couldn't put them on. That's 14 oz I drug for 5 weeks and never could wear. After 3 days back home, I could once again see the bones in my feet and ankles. I'm now glad I didn't abandon them.
We all have our quirks. Mine is trying to pack lighter than last time. I think I've reached my downsized limit, unless I magically become a size 8 again.
