American Apparel, one of my favourite shops, is a sweatshop-free shop (so no child labour, for example) with awesome clothes for men, women, children and dogs (!). This brand recycles (check their vintage collection!) and tries to find other ways to do its bit for a better environment. Besides, AA employees feel strongly about subjects like immigration and sexual orientation. This good initiative appeal to loads of people. Therefore, AA has opened shops all over the world. Another good thing about AA is they use normal women in their campaigns. Not those too skinny models, just normal shaped people and sometimes even pornmodels (!).
They also have a shop online: store.americanapparel.net/
Enjoy sweatshop-free shopping!
