2. Elaborate dresses for the bridesmaids
In many countries, presidential motorcades have three or four identical cars. The idea is to make it hard for anyone trying to attack the president to know which car to aim for.
The tradition of dressing bridesmaids up in elaborate dresses to rival the bride’s came up in a similar way – people wanted to get any evil spirits in the area mixed up about who the bride was. This tradition has since evolved to make bridesmaids’ dresses appear distinctly different.
