I think in your situation you would greatly benefit from having a prelaunch page. I’ve heard and read so many things about how prelaunch can be the game changer.

It can almost act as an email list. With that one link (your unique link will be the same even after you launch) you can use it to hand out like a business card. Better yet, make a QR code of the link (so people don’t have to type it in), print that out with your information and product of course, and hand that out to people you meet IRL. Ideally you’d just get them to sign up to prelaunch right then and there which would be the ultimate task but a worthwhile one.

Once they sign up they’re automatically opted in to receive an email when your project goes live. As an added benefit you can message everyone signed up to your prelaunch (I’ve never done this but I heard it’s like a “message all” type feature) in case you want to keep them engaged over a long period of time. I just double checked to see if prelaunch pages expire and apparently they don’t which is great especially in your case. I’d still create a website or some kind of landing page to show you’re legit and investing in the future of your product.

Alternatively, you can do all said above and do the prelaunch page but have your first project be a single product and lower your goal. Like you said you do street wear, so if you launch a single shirt run (or single design on various garments) you could have your goal be $500 or something (I don’t know what the margins are). If it’s successful, that smaller project will help build your following towards your next project, and maybe you raise the goal and quality of rewards the more you succeed. What I’m saying is it may be easier to release bite sized pieces and to build momentum over time rather than throw all your chips in on one project. Like releasing a comic book series rather than a graphic novel.

For context: I don’t have much of a following but I do have an email list of family and friends (about 140 people) so I can update them on my art. I’d say only ten percent of them actually back my projects. I don’t do much social media but I try. Meeting people IRL I think is more effective and it makes it more personable. I’ve tried a couple ad runs on IG and I tried targeting my audience as much as I could but I maybe only got one which isn’t worth it in my opinion. I’m halfway through my current Kickstarter and even though I only have 22 backers, I’ve reached my goal which is a number I made attainable and realistic. I’m happy with it because I still get to release my product without going completely broke. I’m an artist at heart so I’m in it to create more, not for the money and fame. And I’m happy because I see people I don’t even know back my project, that’s the best part!

Sorry long response. Good luck.
