That is your opinion, and you have the right to present your observations.
There are some who aspire to emulate that trashy look as the pentultimate in the newest fashion wear.
There are others who believe that someone who goes out in public dressed like that should be stoned to death, the latter being mostly of similar religious persuasion as the zero himself.
Making observations, and presenting opinions are in fact a good thing, and should not be summarily dismissed based on the age of the person under discussion.
My personal opinion, (if you are inclined to be curious)is that Momma knows EXACTLY what she is doing, and is using the child as the canvas on which she makes her statement.
I for one, do not agree with the statement, or anything else for that matter that comes out of the mind of Mz O, and will more than likely opine on her choices from time to time, including what venue she chooses to present same.
I have no issue with anyone expressing the wrongness of allowing the girl to wear that shirt. And I agree with your perception of Miz O. But I think that is rather typical of liberal parents, don’t you? Indoctrination starts early.
