Personalized Not a Mermaid Youth T-Shirt. She had so many adventures under the sea, you see. Now, she had given up her tail in trade for raising a child with a prince who was never home in the castle. Raising a baby alone, at the young age of 16, really didn't have too many perks. Let the good times roll in a durable T-Shirt that takes kids from school to play in an amazing array of colors. 5.0 oz., pre-shrunk 100% cotton. Seamless 1x1 rib collar.
