I was skeptical to buy this product because of the sizes that are available. My son is wearing 2T clothes, and I was unsure which size to pick. I went with the 2T-4T. We received the costume today, and I tried it on my son. It fit pretty well. It's a little large because of being 2T-4T, but even though it's a little bit big, it still looks good on him. He'll be ready for his Halloween pictures. I gave the product a 4 star review because the material the costume is made from isn't the most durable. I would have liked to have seen better material, but I only paid $19.95 for the costume. You get what you pay for I guess. I'm not complaining though. I'm only going to have my son in it long enough for some Halloween pictures and video and that'll be it. He's too young to take trick or treating yet, so I'm not concerned about the material. It's good for the period of time my son will be wearing it.
