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, Green Eggs And Ham, 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 Cat In The Hat and the popular characters from the book Thing 1 and Thing 2! The story was introduced in 1957 and is set on a dreary day that turns wild once the Cat in the Hat shows up! 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 striped print pattern. All 3 of the clothing articles have a great stretch fiber and are made of 60% cotton/ 40% polyester.
