I think as a first-time entrepreneur who is non-technical, you should focus 100% of your energy on your clothing business with your buddy. There is far less required to make a clothing business a success than a startup run by a non-technical founder. I don't mean to trivialize the challenges of running an apparel company (there are many) but comparatively, there is a greater chance of you having success with the apparel business than a startup.

But you *reduce* your chances of success by diluting your focus with other ideas.

Happy to talk to you in a call about starting off on the right foot with a cofounder.
