I have a 3T for my 3 year old son (he is slim and in the low height percentile). For reference, he usually wears Gap 3T pajamas. I think the size and elasticity are exactly the same. These pajamas are so soft and great quality. They are slightly more expensive than PJs but in the same price range as Gap. I usually buy Gap pajamas on sale but they were for a special occasion so I spent a bit of money. They look so cute and are such great quality, I'm so glad I bought them!
