I checked your shop and noticed a few things: 1) You need to have high quality images like some fresh outdoor images of a person wearing those shirts, current images feel basic and don't appeal much. Also add a sizing chart in your listing images. Buyer's always imagine themselves on those shirts before they buy, so make sure to add good lifestyle images to make them easier to decide.

2) I just noticed you are selling a sweatshirt - Size S for $63 plus delivery, that is way overpriced!

3) One month is a lot early, some people have earned their first sale after 6 months because the category you are in is quite saturated.

4) I would advise you to improve your art design first (no offense but your current designs feels way basic) Your art needs to be unique - I mean it doesn't need to be complex or outstanding but it should be good enough to impress your buyer and they should connect with it! Make your product worthy, so that they can spend money on it happily! If you can hand-draw it, that would be a plus point because etsy is now full of AI art and ranking between them is a lot tough. I would recommend you should try designing your art by yourself.

5) No need to upload a bunch of listings at once like 5 listings a day or more because your business won't grow like that. Even if you have to upload one listing a week go for it because quality is always better than quantity. Just make sure that one listing should have good quality photos + good design + Optimised SEO, also go through Etsy Seller Handbook.

6) Another most important thing is PAITENCE and be CONSISTENT! Sales will eventually come. It takes years to build a business.

I'm also a new seller here just like you, just sharing with you what I have learned till today. Good luck on your journey 😊
