I really like this costume. I put it on my son when we received it just to try it on. He will be a little Vampire this Halloween. He is 16mths old and the 12-18 mth size fits him perfectly. I intend to put long underware under it on Halloween night. My son is 30in tall and the pant length is perfect. If he were any taller we would have issues. I love the cape. It stays attached. It also includes easy access for diaper changing. The fabric is a little delicate and has a satan look to it. I do not intend on him wearing it more than once. It looks like it will hold up just fine but I wouldn't recommend it for several uses. Children this age are everywhere and into everything so I'm not sure how it would hold up. It is soo cute though and I love it.
