Pretty easy to get on and off my 11 month old.  Only drawback is that it's a jumpsuit style costume, but doesn't have a zipper or velcro in the back - which means it hangs slightly open. For October in Ohio, that's not warm enough for a baby.  That aside, the costume is adorable!  It's a nice, soft material that didn't irritate my son's eczema - even though I didn't have time to wash it beforehand.
