These were a gift to my daughter. I have to say the "one size" leggings was a little worrisome. She had a baby, was losing weight, went from a size 22 to about 18.  Would these leggings fit???

Happy to say yes, they fit post baby and 3 months later continue to fit. She needs a 32-34 inseam and these are definitely long enough.  Very pleased with this purchase.
