Her messaging is a bit all over the place tbh.
If you have the money to spend on something like that, work away; I'm sure some of her followers do.
In an ideal world, of course it's better to buy something of higher quality that will last and can be handed down numerous times.
But a lot of families have no choice but to use fast fashion, as it's the only option budget-wise.
I don't think families that have to make that choice should be made to feel bad that they are promoting slave labour, or anything of the sort.
I wouldn't be following Chupi to get "relatable" content - she's a multi-millionaire, from a very privileged background; she will only be relatable to a very select cohort.
I don't think she takes criticism very well, I'm going to guess that she'll pass comment on "not being an influencer" whenever she posts a link or recommends something from now on. If you're on a public insta, with a sizeable following, and are recommending items... you're influencing gal!
