A few weeks ago there was a thread ( might have been a wedding guest one, not sure) on which somebody linked to some shoes. I thought I'd saved the link, but can't find it now!
The shoes were flat, almond or pointy toe, with a T-bar, and were two-tone. A few people commented that they liked them, or they'd got them, and it turned out they came in a range of colours. They were eminently suitable for a party or wedding, quite dainty looking, and I think might have been suitable for wide feet.
I'm really hoping this description rings a bell with someone - of course now I have a wedding to go to, and can't go in my trainers!
