Once again, I feel that people assume rich people are paying a lot of money to dress like hamburgers for a night. In reality, fashion houses buy tickets and allocate them to celebrities, who they dress to show off how they can make hamburger shaped outfits.
it would be wiser of the ultra-rich to display their wealth in private; when it is public we can see--literally--how their tax cuts allow them to waste millions of dollars on absurdly extravagant costumes of no benefit to anyone.
granted this is a fund-raiser, & without providing a platform for vanity, by keeping the displays private, not so much money would be raised.
