No! When I wrote "nobody should wear anything they didn't actually want to wear" I meant what I said; exchanging a dress code that annoys me for a dress code that would annoy somebody else instead is only moving the problem around, not solving it.

(Secondly, I've never liked Rocky Horror much myself, so that dress code would annoy me at least as much.)

I realise I'm making your wedding more complicated but I would rather wear something I find uncomfortable that you like and everyone else is wearing...
