Under the Sea Summer Pajamas


My little one is fascinating : he wants to be an ichthyologist* and wants to switch from playing the violin to playing the electrical guitar...

Instead... I designed this print for him: all different fish and sea creatures are happily listening to a large blue musical octopus, playing a double-neck electrical guitar... Blue whale and sea-horses are dancing around

All the sea creatures are in many shades of turquoise and light blue.

This print also exists in a romper for the new baby...

I learn from my little one about Ichthyology, also known as fish science, is the branch of zoology devoted to the study of fish.

Shorts are too long (hit

Shorts are too long (hit far below their knees) - they’re usually true to size. Also the seams on the shirt don’t line up correctly. Very narrow body but shoulders are wider. Love the long sleeve pajamas but having a tough time with these short sets

Best pajamas ever

These pajamas are the softest and best quality pajamas I have found. Our little boy (almost 2) loves the sailboat and ocean patterns. We even wear the night shirt during the daytime because he loves to point out the fish, octopus, and sea turtles. Perfection! I wish they made these for adult kids, too!
