How would this work for a luxury item, original/ new fashion branded products, in its early stages of marketing? (What are the risks and benefits)

Luxury items are not common in groups, but I have a friend, whose focus is on customizing luxury beautiful dress for women, got very high income in her WeChat groups. She generated 3 million RMB in one month from just one of her WeChat group.

Normally the bestselling item in WeChat groups is below 1,000 RMB. If you want to sell luxury item in WeChat groups, you need to gather your customer first. It's OK that people don't buy at first. After they feel the quality and taste of your product, they will gradually order from the group.
