LENSOUSBaby Boys' Doctor Costume Bodysuit

Why is this for "baby boys" specifically? Can a girl baby wear it? or is that too absurd?

Why is this just for baby boys?? was going to buy, but i won’t support a sexist company. anyone know of a good company with a similar product?

The direction say dry cleaning recommended. Has anyone just used the washer and it’s been fine?

Does anyone have a size 0-3 mos (labeled 60) to compare measurements and is cap one size fits all? Mine is far wider than pictured!
