I have a large 3 year old and they fit him in a 4t for at least a year. They are actually a little big to start with but you don't see it and the only thing that gets smaller over time are the leg/arm/head holes. Everything else is very stretchy and soft, and these pajamas look very much like homewear. I think I could put him in the playground with that and no one would notice. I like colors, my favorite is dark green. Nothing washes out or loses its shape and I wash/dry them at least twice a week.
