I bought the onesies in two sets of sizes for my unborn son. I can't wait to put him in them. They are adorable. As for size, I can't really say because he's not yet born.
First day for Kindergarten
These shirts are very well made. The colors are exactly how they depict in the picture. We ordered a 5T and it was true to size. My little boy is going to rock his first day of Kindergarten in these awesome shirts!
