These PJs were super cute. I read reviews about the quality of the fabric not being great however I thought they were very soft, stretchy, comfortable and the color has stayed well through washes. They are lightweight and great for summer. MY ONLY CON: the shorts are very short and ride up even more so they end up looking almost like underwear. I wished the shorts were longer.

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.
