Made from the finest organic cotton these t-shirts are not only environmentally friendly, but also free from toxins and allergens that may be found in normal cotton. White girls’ t-shirts with mermaid related prints are perfect for summer. Planet Mermaid t-shirts are extremely comfortable to wear as they are made from combed cotton, which ensures fabric quality, softness and durability. We have also launched a new Planet Sharks collection designed specifically for merboys, with our debut item being a boys’ shark t-shirt in white with blue motif.
