"This costume is absolutely the cutest! It is a good quality, heavy suit. My son is a small 6months, so the head piece and booties are too big for him... I'll have to have a button or snap placed so the headpiece stays in place, otherwise, I love it. October can be chilly where we live. He'll be warm in this suit. The inside of the costume is lined with a satin-y type material that feels good to the skin (although I will put on a onesie underneath). I'm pleased with his first costume."
