Lululemon Cropped Black Leggings

I have no clue what size they are. I bought them and the tag was already ripped out. I know they are significantly bigger than what I usually wear, which is a size 6. The very top waist is 14 inches not stretched out. And the length from top to bottom is 33 1/2 inches. Again no idea what size they are. They could be around a 10?? But I’m not sure. They are super stretchy.
