American Flag location on an officials' shirt

[CTom]

Where is the best place to sew an American flag on a jacket or referee jersey please?
Some old geezer told my partner she was "anti-American" for wearing it high on the back of her jacket. He said "everybody knows it should be above the heart". All three refs that night (two high school) that had flags, had them sewn high on their backs. I have a feeling the distributor sewed them there.My jacket does not have a flag on it. I'll have mine sewn on my jersey (because the jacket has a lining & is tough to sew on) .

Any knowledgable patriots out there with answers?

Thank you.
