- If you are an invited guest at a wedding, it is not good etiquette to wear a bridal gown - even if you happen to be a woman. This tends to develop insecurities in whoever is wearing the official gown - the bride, the groom, the officiating minister, or all three.
If you are not an invited guest, it is not wholly unacceptable to wear a bridal gown as long as everyone is aware that you have not been invited. All will then realise that, in addition to having rather odd dress sense, you are also rather irrelevant, and they will know not to kiss you.
For similar reasons, it is not a good idea to wear a shroud to a funeral.
It is an even sillier idea to wear a bridal gown to a funeral. Unless you belong to a remarkedly hopeful religion. And fancy the corpse.
It is, however, perfectly sane to wear a shroud to a wedding.
I wear a loudly stripped one at most times. It was recommended by my tailor and my funeral director. Who told me it was something appropriate to be buried in. Should the occasion arise.
