It may be worth asking about what to wear. The funeral is, after all, about the wishes of the dead person or the close family so it's polite to dress as they ask I reckon. I've been to far too many this year but it's been interesting in that the dress code has ranged from beach party attire to formal, all black.
What would make you feel queasy - DH's trousers being too tight or did I get that wrong? I probably misread it!!
