The term “big girl’s blouse” is often (perhaps incorrectly) used to describe people who are whimps, who should “man up”.
Now, when this is said, I wonder if they mean that the you are a girl’s blouse that is big or if they are saying that you are a blouse that belongs to a big girl?
If you are a girl’s blouse that is big, then why mention the girl. Surely everyone knows that (traditionally) all blouses are for girls. Therefore under this logic, one should just be called a big blouse.
Alternatively, if you are referring to a blouse that belongs to a big girl, why mention the fact that she is big? Fat shaming aside, a bigger or smaller girl’s blouse are no more feminine than the other, so surely just girl’s blouse would do.
If you were to be radical, you could apply both of the above arguments and just call people a blouse but let’s not get ahead of ourselves.
