I ordered Kid Nation tank tops for my 8 year old daughter to wear as pajamas. Depending on how the dresses are made, she usually wears an 8 or 10. According to the size chart provided, I ordered a large. The length was ok, but it was too big for her in the chest/armpits. Although the tank tops were meant to be pajamas, she refused to wear them without another shirt underneath. I ended up deferring them to the future. Overall I think these are good shirts and my daughter loved the star pattern on the black. It's a shame we have to wait until she grows into them to actually use them.
