It is always traditional to wear black when attending funerals. The color black is believed to make the living less visible to the spirits that came to accompany the deceased into the afterlife. It is said that spirits are attracted to bright colors, therefore it is risky to wear something brightly colored to a funeral. After all, you wouldn’t want the spirits to make a mistake and take you to the other side with them.
It is also disrespectful to wear a new dress or suit to a funeral. This is believed to be an attempt to direct attention from the deceased and their ceremony to yourself, a “Look at me!” gesture. It is said that this is not only disrespectful, but invites evil spirits to follow you home and into your house.
One thing to remember as well, do not go directly home after a funeral. Bad spirits who gather at such things may follow you and try to enter your home, so it’s best to stop at a restaurant for a bite to eat, or maybe do some shopping. This is said to confuse the spirits and prevent them from getting to and in your house.
