Could have also been the fact that it's a post-apocalyptic costume on a bald, white mannequin, which, even if you're not familiar with the costume itself, looks pretty similar to a post-apocalyptic costume on a blad, white woman.
This is like "Oh hey, that looks like a Star Wars blaster" "Umm, you mean you don't recognize Han Solo's blaster at first glance? It was only in half the movies."
or
"Hey that fantasy sword looks like it came from Lord of the Rings." "It fucking should this is Glamdring the Foe-Hammer, vanquisher of Durin's Bane, you fool."
I don't think it is. I've rubbed shoulders with the 1% on a few occasions and they tend to give shit like this the way we give out candy. I've heard of little gift baggies worth over 1k distributed in large numbers, and me being impressed by that was surprising to the person talking about it. He acted like it was $30-$60 when he was talking. It's spending on a completely different scale. Headphones are not a statement. They're an afterthought.
