You're looking at Hanna Andersson brand girls denim skinny fit jeggings/leggings pants in size 130cm (US 8). They are stretchy and have an elastic waistband, 96% cotton and 4% spandex.  They have faux pockets and faux zip design in front, and 2 working pockets in the back.  They have some fading throughout and on the knees, as shown in the pictures.  There are 3 dots, 2 in front and 1 in the back, which I've tried to take pictures of.
