I think 'themed' meals are quite fashionable at weddings these days. I'm planning my own wedding for Halloween (we're having a buffet, which will have a Mediterranean/North African/Middle Eastern slant but not exclusively so) and from what I've read, it seems quite popular amongst less traditional couples, particularly in the States, to have something like tacos, or a hog roast, or only desserts, or some other non-traditional fayre. I think the curry is one of the British equivalents. It is unfortunate for people who don't like or can't eat curry! And yes, it would be unpleasant to end up with your wedding outfit smelling of curry, particularly if it's dry clean only!
This is my second wedding, and even so I find it very odd that couples invite people they barely know (parents' friends). But then, I paid for my first wedding at the age of 31 and will be paying for my second one at 50, so there's no reason to invite anyone at least one of us doesn't specifically want to be there!
