Lululemon pants

Black Lululemon pants, Size 12 WITH adjustable drawstring. Lightly worn, my mom gave me them so i’m not sure what style these are. The drawstring does have a little knot that can come out, i just have a hard time with nails on. (Seen in photos) they come to my ankles, i am 5’3 for reference. (I typically wear like a size 6/8 depending on the brand. I just tie these tighter)
