Sorry for the late response I have just been caught up in work!
My friend has recently had a stack of clothes dumped onto him that he will be using so I would say it's “recycled” clothing but the material he will use to print the designs on will be cotton. He is making both a fitness & casual wear apparel and wants to aim it towards promoting veganism & animals.
His designs will be done in photoshop with nothing too graphic as he doesn't feel it's fair to the overall population to see that. For eg. “F**K TONY ABBOTT” shirts . I would best describe some of the designs I have seen a cross of Sea Shepherd inspired cross with Band merch. Very acceptable for the more mature demographic and won't look silly if your 20+ wearing it.
Quotes such as "Powered by plants." & "Vegans Do It better” will most likely be put into the fitness wear.
One design he is currently doing for Reptile Warriors depicts a crocodiles eye in the middle of the shirt with the reptiles logo stretch above it .

Most of his casual fitting wear will be loose except nearly all his fitness clothing won't be .
I hope that helped answer a lot of your questions & if you have anymore just ask away as I will be seeing him properly this week
