Are there any practices that accompany weddings (and the whole engagement/marriage process) that one has to be careful to avoid because of the prohibition of following in the ways of the non-Jews (chukos Ha'goyim)? For example: engagement ring, walking down the aisle, white wedding gown etc
Here is one:
Many Polish and Russian Rabbis felt that a Chupah should not take place in a Synagogue, as it became customary to exchange vows in a church, so it became Chukas Hagoyim. Many German Rabbis though felt that it is no problem, as it is done in Church only because it is a convinient assembly place, not due to religion or custom.
