In order to demonstrate the integrity of all these commitments and to counteract aggressive greenwashing, many companies emphasize for Fair Fashion their commitment with the help of recognized seals and certificates. Here is a brief overview of the most relevant seals:

If a t-shirt carries the GOTS seal, this means that it is 95% made organic cotton consists.
