"My son is an average size 8 year old and the size 10-12 costume is close to being too tight. It is a tight fitting costume so I would suggest ordering a size up like we did. I used costume express sizing chart to help me decide. My son wears glasses and often has to take them off for masks. The goggles with this are going to fit over them so that's a plus. He's excited about wearing this costume."
"My son is tickled with this knife and ready to use it with his Recon Commando costume. I have to keep reminding him to be easy with it though because it looks like a tough 'stab' would probably break it. You get what you pay for but otherwise a really cool prop for Halloween night as long as we don't break it first. ;)"
