Dear all, thank you for all the suggestions!
Staysfit, you're right about ordering, but then I'm afraid I'll fall in love with them even if they don't go with anything!
Firecracker, what a lovely idea about mixing patterns. I love mixed patterns but I'm not very gifted at doing it myself.
Joy, thanks for the tip on the sock tucking--that will help me with another pair of pants that is slim but not skinny enough so it bunches.
Janet, good to know that the pattern is more versatile than it seems!
And Rachylou, yes, my spring will be cold for sure (when it finally arrives)--so yes, I probably can get three seasons out of these pants (in truth, four, because I always spend part of the US summer in the southern hemisphere, where it's winter!)
