Now it is really difficult to find a quality dress of this type, as on the Internet very often sell fakes or dresses of poor quality. I am convinced of this personally, as recently bought such a dress for his wife and spent a lot of time looking for good variants. But I found some dresses here https://store.newhanfu.com/shop , I liked them very much and ordered one there. I would especially like to highlight that they use the same materials in Hanfu dresses as they did in ancient China. Maybe not exactly the same, but as similar as possible. It is very cool, so I think you can look it up there. Good shopping!
