Lululemon Leggings Size 10

Comfortable and stylish black leggings , unfortunately the seam on one leg on the inside of the thigh has come undone , I have tried to stitch both spots ones still holding but the other isn't, Im no good at sewing apparently, so now these have holes again as shown , but if you can sew they would be perfect since its a seam , this issue reflects the price , these do have pilling on waistband and inner thighs. size 10
