T shirt design for children

C'est ce qu'une entreprise en/au(x) United States recherchait pour leur t-shirt design

I am considering starting a clothing line for children with Japanese tattoo inspired art, Japanese cartoon style picture, anime, oriental inspired artwork, you may add some catchy or funny phrase, that atract parents to buy highly preferred, Colorfull, or monotone are welcome.
My target customer are parents who love oriental art work, oriental tattoo art, or children who love manga styles artwork and Japanese cartoon style picture, for boys and girls. Thank you I am looking forward to see any new idea.
