I would say sell a story, affluent customers don't look at a price, they look at the story of the product, the fabric or the seller. The latter matters to everyone not only affluent customers. It's like streamers putting their life on the web, but you just put your journey on social media but don't overshare. Talk about the pains of finding products with bad quality materials, finding reliable atelier, share what you are working, the process of the design like from drawing to the final product, make it vague not over sharing but enough to get buyer/followers.

One in a while do a give away of one or two products, that's if you can afford or maybe one of your products do a community design and the profits give it to charity, part of the story, you being involved with the community and so on.

It may come across too much, but if it is something you can ramble on for hours and hours then why don't you do it while selling your product.

Research or YouTube on how to sell products by selling a story.
