The Kardashian Power for Good

Would major celebrity endorsement be a make or break situation for a sustainable brand? I literally have no idea! Yes, it could work to bring a certain brand or product to the attention of a large following, but would it change them for the long run? Or would they switch to the next big thing as soon as their favorite celeb endorses something else? Could it harm a sustainable brand if a not all-sustainable celeb endorses them? Like I said, I don't know. I have a lot of thoughts about it, but they change all the time. I'm curious what other people think about this! :)
