Remember, a funeral is not the right time to make a fashion statement. However, if the dresscode states no black, avoid the colour entirely- men can still wear black trousers.
It is also considered poor taste to be on social media during a funeral, like Instagram, Twitter, Facebook, or Snapchat. Photography, unless authorized, is usually disapproved of during the funeral service. At the reception following the service, it may be okay to take photos if you are close to the family, especially if you haven’t seen them in awhile. Ask before you snap a picture, and watch what others are doing.
For example, when you approach the family, move at a slower pace than you might normally, keeping your facial expression neutral. In your most serious tone, say, “I’m so sorry for your loss. We’re all going to miss her. " Before bringing flowers to a funeral, check with the family members or with the funeral director if it is appropriate. You can offer your sympathies by saying, “I am very sorry for your loss” or “I am here for you and your family if you need anything. ” If you are at a loss for words, you can simply offer a hug or bring a sympathy card.

Generally, laughing at funerals is unacceptable unless it is warranted. An occasion for when laughing is warranted is when the eulogizer recounts a funny memory about the deceased. However, stay on the safe side by following the family’s lead. [4] X Research source
