JOYSPELSWomen's High Waisted Gym Leggings - Full Color Printed Leggings, Non See Through Yoga Pants with Pockets

How do these hold up after multiple washings?

Can anyone say how long these are? At 5’ tall most leggings are very long for me..

I previously bought these in size 'M' but the sizing is now numbers, is there a conversion chart so I know what size to buy (M is too big for me now)

Problem with sizing, ordered a 14, then a 12, both came labelled as 'L' and too big?
