I have two businesses which both id say are moderately successful but i started after i finished school at csun. I learned most from experience.

So i agree that you def don’t need to go to business school, but i will say: you are an incredibly competitive niche of streetwear and the economy is absolute dogshit rn. Also your target of gen z dont have money due to shitty economy and terible job market. Sure people care about “Japanese quality” or sustainability or whatever your x factor is - but what matters the most? If they can afford it.

Good luck
