Joseph, we learned if you are visiting you keep your own minhag hamakom. Davka I heard it’s assur to follow the place you are visiting. Let’s say a woman from wears only tichels, as that is the minhag hamakom, goes into another city for a wedding, and she is the only woman wearing a tichel at the wedding since the second city, the inhag is to wear sheitals.
I learned it’s assur for the woman to wear a sheitel. She has to wear her tichel.
Minhag hamakom doesn’t go by your shul, community, bungalow colony, nor street. It goes by the top rabanim in the city.
