AIBU to want to wear black to a wedding?

[Cookingmonster]

I mean, I don't really know the couple, my husband is goodffriends with the groom, I''ve met him a handful of times and her only once. I'm usually against wearing black to a wedding but it's the only dress I have that goes with the fascinator, jewellery and shoes. It would mean not buying another dress!
So, tell me AIBU?

Depends on the kind of couple/guests, perhaps, StarDust? I genuinely have never experienced, and can't really imagine happening, a wedding where the colour someone wears causes an upset or makes people stare and judge. Or leave them out of the wedding photos.

I would say wear the red one. are you sure the accessories dont work? - try them out when are asking ppl. Or can you borrow an essential accessory if necessary? Surely any shoes, bag jewellery that you'd wear with black or white will go with red unless they are red or pink?
