Great pjs
Size: 10, Color: Under the Sea
Just what my son needed comfy tshirt & short pj combo. These are comfy and 100% cotton. I can say the quality is good after being washed a couple times but as all things the color fades. But overall these have been very useful. Definitely would buy again.

Size up
Size: 6-7, Color: Under the Sea, Size: 6-7, Color: Under the Sea
My 5 year old is at the 50th percentile for weight, and the size 6 fits him perfectly. Almost too perfectly. I wish I would’ve bought a size up, so he could grow into them. Material is soft but strong. Overall happy.

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.
