Any Tips For An Upstart Clothing Brand?

Hey, let me introduce myself. My name is Mike I am 22 years of age and I am a music artist. Now because I’ve constantly received great feedback on my designs I’ve recently I’ve decided to start selling merch based on my music and my ideals so that I can help fund my career. Now this is its own brand while it’s also apart of my music brand. I was curious as to how I can actually get some sales. So far I only have 2 sales from friends and I really want to get on top of this. I’ve created a buy 1 get one half off sale and I’ve also created a promotional video Here I also added my song that the specific clothing piece is based on and even had it change for each clothing for the promo video.

Now I just started so I was hoping for pointers and tips to make some sales. I don’t need crazy sales I’d be happy with even 5-10 a month tbh. I just want to get on my feet and would like advice. What do you guys think? Please help.

here’s the link again to my promo just in case
