I designed some apparel for the swimmers at my high school, that was approved, which was going to be produced by my school's clothing manufacturing partner, but (long story short) the company was unable to make my design.
I found another company that has no relation to my school that can produce my apparel. I want to repurpose the apparel for the entire student body, take on this project by myself, and sell the apparel personally, but it contains my school's logo in the design. Would it be illegal to sell apparel to my fellow students if it has my school's logo on it and is not strictly approved or managed by my school? Does making a profit versus just selling them to break even change anything either? I go to a public school in the US by the way.
