First, this costume is extremely durable, heavy material, not cheaply made at all, and really cute. My son got a ton of compliments. However, there are some drawbacks to keep in mind when deciding on ordering this costume.

1) The age and height/weight of your child.

I have a 4 year old son and he weighs about 40#'s. He is pretty normal height and weight wise for a 4 year old (pre-k in school). This costume was too heavy and bulky on him. It was big on him. Not terribly oversized, but it was a little difficult for him to keep his arms through the arm holes and it affected his balance/mobility on the length and width. The "under stuffing" is terrible, and I'll cover that next.

2) How long will your child be wearing this costume?

There are 2 parts to this costume. The outside part you see, and an inner part to stuff so that the costume takes on the round angry bird shape. This part of the costume was terrible. There are 2 pouches that you must fashion into a slip on "under shirt." There is no way a full size pillow will fit into the device like they instruct you to do. No way. Even if it did, my son could not have carried around that weight. I used miniature pillows (approximately 6x10) in each pouch. The pouch has 4 spandex type straps. You tie the top 2 of one to the top 2 of the other so that they form a "stuffing tank top" to slip over your head. Then, you tie the sides together to fasten it around the waist. You then put the outer costume over this. My son could not keep the "stuffing under shirt" from slipping off his shoulders, so I had to keep reaching under his costume to pull it back up. Plus, it was heavy and didn't make much of a difference in the appearance of the costume because it was so big on him anyway. He wore it to the school Harvest Carnival, which was crowded, and he was miserable with the under stuffing. I took the under stuffing off and carried it around with me all night. It was heavy to carry, so I'm sure on his small, 4 year old frame, he was very uncomfortable.

3) The head.

This costume is heavy, thick, styrene type material. The head of the bird slides up over your child's head, but it gets hot quick and the "comb" of the bird's hair doesn't stand up freely on its own. Not on the red one anyway. My nephew wore the black costume and the "comb" was smaller, so it stood up better. You can stand it up to snap a picture or two, but once you start moving, it falls to the side.

So, overall, your like or dislike of this costume will depend on several factors. Oh, as far as "extras" you need for the costume, there aren't technically any, but I paired this costume with black cotton stretch pants and a black long sleeved t-shirt, and it looked nice. I hope I have thoroughly covered all facets of the costume so you can decide if it is right for your child or not. If you have any questions, I will gladly answer them.
