Review on 👕 Premium Quality Buyless Fashion Little Cotton Undershirt - Boys' Clothing and Tops, Tees & Shirts by George Kapoor

I bought each of my boys a set. I bought a 6 year old 6-7, an 8 year old 7-8 as they always run small. He's put on some weight so is a little stockier and no taller size is necessary for his age. Tried 7-8 on it and it's tight. Worn by a 6 year old, fits perfectly. It has stretch so it might fit an 8 year old but it was quite uncomfortable for him and hasn't even been washed. I don't even want to see how much denser it can get after it's gone through the dryer. So you should increase the size.
