Yup I've got on the Teemill train and designed some lovely merch.
In line with the ethos expressed in Get Undressed they are organic, environmentally friendly, Fairtrade and all that gubbins. You can check out the specifics here: Teemill Ethics
I am fully aware that a small line of exclusive merch will not do a lot to help the victims of the mass market fashion industry, so please keep an eye out for the upcoming Get Undressed range which will include a donation to charities who can.
