Too tight
Size: 4T, Color: Under the Sea
Very very very small. My 3yo is very skinny and the 4t it is too tight on him. Can't imagine how this would fit a less skinny kid.

Long to accommodate torsos and legs
Size: 8, Color: 4p Dino
These are well made pajamas. The tops and bottoms are longer than I have seen with other brands. I love that because we buy new pajamas when my son's pajama tops are too short or when the rise on the pants gets too low. My son is 6 years old, 55 lbs, and 4'1". I bought a size 8 for him and they fit with room to grow in all directions. The shorts come down to his knees and the shoulder seams are slightly off of his shoulders. Most importantly, the rise is high enough on the shorts and the shirt covers his stomach with length to spare. He should be able to wear these for a couple of years. I don't love the designs, but my kid doesn't really care what his clothes look like, so it works for us.

Adorable, Comfortable, and Durable PJs
Size: 3, Color: Redblue4p
I bought this pajama set for my son, and it was an instant hit he loves the fun dinosaur and space designs. The fabric is 100% cotton and feels soft and breathable, perfect for bedtime. After several washes, the colors are still vibrant, and the stitching is holding up really well with no shrinkage.
