People will think you are wearing batmans utility belt.
to the OP. Interesting idea. You should do some research on business feasibility. How many pairs of shorts are you going make? Who’s going to make them? Who’s going to sell them? What are the startup costs? How will you grow the business. Everything financial, like taxes. In the end business is about making money. Make your decisions oriented towards that goal.
Good luck
im actually taking a class called the “Young Entrepreneurs Acadamy” where middle and highschool students get interviewed to get in and then learn how to and actually start a business. believe me i have DEEPLY researched all of the things above and am continuing to do so. and i had the exact same thought about batman hahaha
