Lululemon cropped leggings

Size 4 Side pockets My sister only wore these a couple of times they were too small on her so she made a knot in the front (pictured) it’s very tight and I cannot get in untied it’s on the inside waist band. I’d say if you want to purchase these you can wear as is I tried them on and the knot didn’t bother me cant really tell because of how stretchy it is.
