YMMV Everlast® Women’s Fold-Over Yoga Pants (Sears) .99
These wash up well, the material is very soft and comfortable. They do run long for me (short legs) but I think they’d be perfect length for average people. They have a bit of a flare at the bottom (think "boot-cut") so they work well with multiple types of shoes/boots, not just sneakers.
