First, the size 8-10 barely fit my very slender 9 year old.  The back seam did not close. The hood was too small relative to the costume. The mask was large and had only 1 awkard thin velcro strap to hold it in place.  It hurt my child's face.  He took it off after a short amount of time and did without it.  The material is your standard cheap costume material, but I agree with the post that the proportions are way off. Overall, if this is the costume your kid wants, it will be tolerable, but if you can talk your kid into another idea you win.
