Ashkenazim and Sepharim
The Ashkenazi custom is to get married under the stars while in its not s Sephardic customs to get married outdoor or indoors just preferably in the day time.
I find it very interesting that the Ashkenazi brides walk around the groom seven times underneath the Chuppah. The bride walks around the groom seven times to symbolise the seven days of creation while the Sephardic brides do not do this.
This minhag does not show how the community adapted to its new environment because the traditions were not based on the new surroundings in the diaspora they could be practiced anywhere and weren't influenced by a new place.
