I am RUBBISH with this sort of thing.
This is my dress (pics).
I can't do heels, not even wedges. I'd try and then within 15 mins I'd be cursing myself for thinking it was ok and changing into flip flops.
On which note, flip flops would be the footwear of choice but I can't risk one of them flipping or flopping off as I'm walking down the aisle.
I've found these which I think might work

But apart from that, any ideas? I don't think gladiator sandals go, which would be second choice after Havaianas. I'm thinking gold or ivory colour.
For reference, I'm a size 16 and definitely cart horse rather than race horse, so dainty really isn't my style...!!
