Sam has gotten kind of fat, so it is hard to get the costume to strap on easily. However if he cannot get it off after about 30 seconds of effort he gives in (which is good for me). Sophia is rather hit or miss. Abby hates costumes (notice she is only 'wearing' glasses) and can get them off within seconds. That said some of the pictures are slightly blurred because once the costume is on, it's rapid fire with the camera.
Here is Sam as an undead rooster (note: the costume glows in the dark!!!!):
