Leggings DepotWomen's Active Workout Capri Leggings

I see that one size is 0-12, which would be too small for me. i normally wear an xl (14-16) in leggings. will a 1x-2x be the same in these?

im 5'11" 150lbs, proportioned built. but will these fit me? there's only 1size fits all? and I wear a size 8 sometimes 10

How forgiving are these on flaws?

I’m 5’2” and want these to hit a little higher on the ankle...should I get the corpus instead of full length to get the length I want?
