I have a six year old whom I buy costumes for; non of which are sexually provocative or racist stereotypes.
When I was 8 I dressed up like a cat. I wore my ballet leotard and dance pants and a cat ear head band. That’s it.
I am an adult woman who weighs 230 lbs and I found plenty of costumes that were neither “slutty" nor a racist stereotype.
As an overweight woman, I can say that I have one of the hardest body-types to shop for (as it is very rare that I find plus size clothing) and if I can find a costume that isn’t a racist stereotype you can too.
