a funeral service ISN'T a sad thing, unless people make it one.
The purpose is to bring all the person's close family and friends together, anyone who knew him and celebrate his life. It's a wonderful thing to happen, so sad it takes such a tragedy to bring it out though.
I believe the make up should be on the natural side, so no red lips, and your clothing should not attract attention. I have been to only a few (Thank, God!) Funerals in my day, because I haven't had many loved one's die. I usually just go in my nicest low key outfit, if that helps.
