Rachel Zegler drama... but a custom dress

Guys I love Rachel Zegler! But she wasn't invited until the Oscars (big news story) until a few days ago, right? It was a big scandal? And then she was included as a presenter. Brad just said on E! that her dress was CUSTOM MADE FOR HER by DIOR. I'm not custom-ordering Dior often, but when I do, I need more than 3 business days notice, no? I'm just sayin' something smells fishy?
