Head to toe full-body costume.

Hands, and especially feet, are very impressive - people loved the look!

The mask is a bit stifling, and overall the thing is hot, so be prepared to take it easy.

As another reviewer stated, use stuffing and a blow dryer to prepare the costume.

I wore house slippers inside the feet, that worked well.

I cut slightly larger holes in the ears.

I did not cut a hole in the mouth; it would have been better, both for drinking through a straw, and especially for talking -- your voice is muffled inside this thing.  BUT, it might ruin the look of the face, not sure.

The shoulder pads make you look like a hulking beast.  I am only 5'9" but looked like a linebacker.

Take a good look at the string ties across the shoulder pads and body back closure -- might want to upgrade them with some string or something more durable; the cheap junk this ships with frays and comes undone quickly.

All in all, a great costume, just try it on in advance so you know what needs to get modified.  Budget about a half-hour to get it set up right the first time.
