From experience. I wouldn’t worry about taxes until you’ve actually made money. You haven’t sold a single item of clothing yet. Taxes arnt your worry right now.
You need to google about being a perpetual traveler. Living fully remote on tourist visas, each country you visit doesn’t have the right to claim taxes from you. And you need to be a non resident of your original country and make sure you fit the criteria for being allowed to ‘leave’ as such.
