Brands need this. If brands only target certain people of certain wealth or financial means you risk damaging the brand. Brands will generally always have accessible products to target those new customers, leather goods, small accessories, beauty, etc.And really, financially, a lot of those people (both the influencers and their followers) shouldn't have been spending that kind of money in the first place. There will always be people with money and there will always be status-conscious people who want to buy from luxury brands.
It’s required to 1. Maintain their reputation and be desirable 2. Turn these consumers into loyal customers. There may be shift of turning to minimal brands, less logo heavy or to lesser known brands due to too much exposire, but they will just change tactics like be less logo heavy, limiting supply or trying to convince there’s scarcity.
