Review on Fruit Loom Little Boys White by Elton Luo

I was looking for a plain white t-shirt for my son to wear under flannel shirts, button down shirts etc and found this set of 5 at a good price . Ordered what was advertised as a 4T based on the weight chart provided but when it arrived the package was actually a size 4/5 and was rated for a 10lb heavier child. The sizing options didn't reflect what was actually in the package. They are cotton so I can make them smaller but I wouldn't buy them if the size is right.
