Context:
I am 65. The funeral is for the 85 year old husband of a rarely seen in recent years cousin of my mother's.
Altogether I think I met him 2 or 3 times...but I was invited (and went) to the ceilidh they had for their wedding reception (they were a very mature couple).
I have a smart black outfit, but I'm not sure if that would be too much, given that I didn't know him that well. I would be going to show my love and respect for my cousin, rather than out of overwhelming grief.
If I don't wear the black outfit I do have a pair of smart grey trousers and a darker grey top I could wear. My husband will be taking me as I'm not allowed to drive, and he has a very smart black suit he will be wearing.
Do I wear the black outfit? Or do I wear grey?
