These are officially licensed Dr. Seuss pajamas for kids! many of us grew up reading all the awesome children's books and fun stories from Dr. Suess. There is Fox in Socks, Cat in The Hat, One Fish Two Fish, Red Fish Blue Fish, Horton Hears a Who, Myrtle the Turtle, The Lorax, and those are just a few. Another fun one portrayed here on this magnificent Dr. Seuss 3 piece pajama set is Green Eggs and Ham! The story was introduced in 1960 and gave you an idea of just how good Sam-I-Am thinks Green Eggs and Ham are! Trust him; you can eat them anywhere! Each set of pajamas comes with a shirt, shorts, and pants. The shirt features a ringer-style look with a detailed front design. Both the pants and the shorts come with an allover polka dot print pattern. All 3 of the clothing articles have a great stretch fiber and are made of 60% cotton/ 40% polyester.
