I've been mooching on the net and found this style, which I think fits the bill for what I want. It also means I can go back to looking at regular tiaras rather than pin my hopes on finding a crown I like.
It looks like I'll need a hairdresser now though or, at the very least, find a talented friend or family member that is coming to the wedding. I can't see me managing to do that style myself

I hope that my child, looking back on today
Will remember a mother who had time to play;
Because children grow up while you're not looking,
There are years ahead for cleaning and cooking.
So, quiet now cobwebs go to sleep.
I'm nursing my baby, and babies don't keep.
