It took me forever to finally find a suit for my 3 year old. He's on the plumper side of average size. I bought him a 5T and they fit him really well. We had to hem the pants but the jacket, waistcoat and shirt fit perfectly. If your little guy is slimmer, I'd say maybe smaller. This costume is also very fancy and worth every penny.
