Lululemon full-length ruched-waist wide-leg pants

Black pants with super cute waist. I have no idea what style these are. They might be vintage Lulu, really unique and cute. The waist is compressive and flattering, super high towards the ribs with ruched detail. It makes your waist look really compressed while the legs are flowy and comfy. These are full length on me and I am 5’9” with long legs. Super cute seams down the middle butt down the legs. These have a little fading (can be seen waist detail photo). They are slightly thicker (def not a wonder under or align material). Lots of compliments when worn!
