There are loads of issues with this. Firstly, how will you or one verify that you have worn the jumper for the said 1 month. How long will you be out to advertise the said product? and countless more issues. I dont think anyone will be willing to pay for this. Good Luck anyways.
i can wear it everyday and take a picture without my face and i can also hold a paper and put the time, date and my username next to the jumper or sweatshirt of your choice . How does that sound
I agree, there are some major issues.
How can you wear it every day? It will get all sweaty and smelly and you will produce the counter effect, people will start to dislike your jumper along with the logo on it
Don't you agree? But if there are people willing to pay for wearing jumpers you can count me in. But I would wear it only 2-3 times per week.
