Yiu understand that there is an agency pushing and promoting her, right? They negotiate stuff and then Lottie posts what she posts. She often posts small brands too that don’t have a full marketing dept and don’t necessarily know how to negotiate an influencer marketing contract.I think if brands are stupid enough to gift her £500 dresses that maybe won't fit her then that's on them tbh. They could have asked her for photos to pre-approve before she posted if they are bothered about how it looks before she publicises it. I'm not defending Lottie coz I think she's an absolute moron but we know she has no scruples when it comes to advertising or promoting things as long as she's getting the dosh.
That said, she was definitely rude and it's simpler to ignore or delete the comment than get snarky. She lives in a bubble where 99.99% of her followers spend all day bestowing praise upon her so there's no need for her to get het up by one very occasional negative comment that comes her way. That shows how fragile her ego is.
