Lulu lemon lululemon Navy cropped leggings size 2 with back zip pocket

Size 2 gently used condition. Has a back zip pocket for storing keys etc. These have an 18” inch inner inseam. I’m not really sure how Lululemon sizes—I know they do by inches but I don’t know if they measure the whole length of the pants or just inseam. This is the shorter measurement. The longer one is about 25”.
