If you’re a smart company you’re not going to insult your customers by calling them fat or lard asses. You use positive sounding euphemisms that get potential clients interested in your product. “Plus-size.” “Full-figure.” “Women’s sizes.” Marketing 101.
But hey, it’s Walmart and they can do no wrong and overweight women (who obviously know they’re overweight, that’s why they’re looking for larger sizes) don’t deserve to be treated nicely by vendors.
Really, they don’t need costumes. They could just go without clothes, and perhaps toss on some fake blood for effect.
That would scare the hell out of me, and I’d definitely run in the other direction! lol
