Denim like lululemon leggings

I’ve had these forever, and pretty sure I bought them off here maybe 7-8 years ago??? I loved them just never wore them. I may have worn them twice within having them. They do have some slight piling. Just needs someone to sit there and pluck them but otherwise amazing condition. They look like a sort of denim and thick in my opinion. Says a 6 but I think fit more like a 4 personally.
