Lululemon Leggings - Black High Rise

I LOVE these leggings but they are too big (didn’t know this brand stretches as you wear them). Bought in store so I don’t know material type or length (I THINK theyre Wunder Unders, likely 25 in length). They are soft but not slick (almost like cotton). I am 5’ 6” for length reference. Worn twice cause i didn’t wanna believe they didn’t fit. Washed in cold and NEVER put in the dryer.
