Everyone is going off on Cait and the 20.000$ dress. But how do we know it's her doing? Don't actresses get the dresses from the designers for free to wear at these events to show them off? I doubt she bought it herself and is now asking that price.
I think that is slightly delicate.. Naturally, it is really common for celebrities to wear dresses/clothes for PR. So there is of course a pretty big possibility that Caitriona did not buy her dress. So then if that is the case here, the control that she has over pricing is frankly quite limited.
She might have some power of decision, but I am not convinced enough to give a solid answer 🙂
