HUEWomen's Ultra Soft Cotton Leggings with Wide Waistband, Full and Capri Length

How high up do these go on the tummy? How wide is the waistband? Is it comfy or does it cut you in the middle?

I am 6'2' sz 8 where is the length???

Would these work well under a form-fitting sweater dress?

Are these true to the color shown?
