Bridal halloween costume

The party is pretty much planned and I have all the supplies I need, I have started David's costume and my own. I had planned to wear a charity bought bridal gown and put my hair up for Bride of Frankenstein but she actually only wears a sort of bed sheet bandage combo rather than a formal wedding gown. I'd love to do my hair up and I'm sure everyone will recognise me, it would be a very agreeable costume.

But I am tempted to modify the gown (it would look great) and tint my hair purple to become Tim Burtons corpse bride, Emily. This would be more authentic but I'm not sure I can ruin such a gown (even a bargain one) with good conscience.

I'd like some opinions please, do I modify the gown and paint myself as a zombie (I do love a good zombie!) or do I keep it decent and do a passable bride of Frankenstein? Decisions decisions! Please vote on the right hand side, opinions are greatly appreciated : )
