my three year old son is very small for his age and he is at the lower percentile for height and weight. i bouth these shirts under the inpression that they were size 3t and when i got them they said 2t/3t on the package. i figured that would be fine since he was so small but after one cold wash and tumble dry on low heat it wouldnt even fit him. i say this was sized to fit much smaller kids and the advertisment wasn't honest since i only saw the 3t untill it arrived at my door. not happy with this purchase.
