Got this for my husband for Halloween. Our boys were Mario and Luigi, and I was Princess Peach. I took a risk since my husband is a larger guy (XXL-XXXL). The mask fit OK. He wasn't able to velcro the collar around his neck. The shell was never going to fit. He is much too large for it to work. The mask has REALLY good detail. The boys love the shell and wear it all the time.
