Adorable costume, but not the easiest to get on.  The only opening is from the bottom and there's not a lot of give (or any for that matter) to get it over shoulders and arms through.
The had is cute and definitely makes this costume great...BUT, it slipped down all night, covering my sons eyes.  I eventually put a baseball cap on underneath it so he could see to walk.
The velcro under the chin also didn't hold.  I ended up cutting holes in the bottom of either side and slipping some string through to tie it under his chin.
