Made $400 in revenue in my first month on Meta Ads with niche apparel brand. Looking for suggestions / resources.

Basically as the title suggests. I launched an apparel brand in late January (think Johnny Cupcakes, but replace baking with a different niche). This definitely isn't your typical Printful + Shopify dropship store that looks like it was made in a week. I'm a professional web developer and spent all of 2025 building the brand / website.

• Made $400 in revenue through ads with $550 ad spend in the first month of the public launch.

• Got my first sale for 5 shirts worth $150 in the first 48 hours of turning on Meta Ads.

• Current ABO is $10-$12 per ad set. Usually running 4 at a time testing different things out.

• All my sales have been from older clientele from ages 45-64.

So far all my ads that have converted into sales have been simple, straight to the point static images of the t-shirt and then a simple headline / subheadline / CTA footer. I dabbled a bit with animating them in Canva, but those didn't turn out well. Will probably mess with video more again.

Here's my ask:

• For those that have worked on niche apparel brands, what has worked for you in terms of creatives?

• Is there any general consensus in terms of single interest vs multi interest audiences?

• Also looking for any good resources to study, specifically ones that focus on niche / street apparel brands. It's been hard wading through the sea of gurus that only offer low hanging fruit and are just trying to get you enrolled in their courses.
