The costume came quickly and included the mario hat, the jumper, the gloves, a mustache and an inflatable belly to wear underneath, so I guess we did get the Deluxe costume, unlike some other reviewers - we purchased from Costumekingdom. The mustache is huge, my son (age 6) did not like wearing it, it covered his whole mouth (pretty much like the kid in the picture), so instead we took a black face paint crayon and just drew on a mustache.  He also wasn't interested in the inflatable belly.  He looked just fine in the costume without that too.  The gloves are big - I can easily fit my hand in with room to spare.

The costume velcros together in the back, this kept coming undone so I used safety pins to connect it.  My son was able to wear regular clothes underneath and it looked just fine. He usually wears size 8-10 and that's what we ordered and it fit just right, so it seems true to size.  He worse this on 3 occaisions (outside of the trying it on and showing it off to others) - we had a huge Halloween party at our house and he literally ran around the house and yard and jumped in a bounce house for hours in it.  Then he went trick or treating twice.  The costume still looks great, so it has held up well.

I felt the costume was well made and would recommend buying it for a kid's dress up collection if they were really into mario. I'm pretty sure my son won't let me put this away for a while!
