A great source for groovy kids' tees is the French site Monsieur Poulet or Mr Poulet. Here you'll find some cute tees by a range of designers. Artists can submit designs that then get reviewed and voted on by those who have registered to participate on the site. Winning entries then have their design printed on a garment for women, men, or for children. Here are some I liked from the current range viewable for kids. The tees are limited editions and you will see some of these have sold out:
Crazy Castle or Château fou by Aphte
Pffuit by Kiko
Princess or Princesse by Chamo
I guess a cloud or Devine moi un nuage by Lulu
Adorable Grizzly by Grootfontein
Ninja by So Cuute
Star Maker by Luce
Monsieur Poulet delivers Fair Trade clothes and accessories; garments are made from organic cotton, and designers of the winning entries are paid. Find out more about how it works here.
You'll also find on their site these clever postcards by Monkey Design Ltd that can transform into all kinds of wonderful creatures:
Monsieur Poulet - great site, great designs, great idea!
Please forgive any poor translations - I do not speak French!
