Wedding shoes

So, I've got a few weeks to find a fabulous pair of amazing Mo-style shoes for the big day.  I'm having my first dress fitting and my seamstress, Toula, insists I bring shoes (I know it's the way it goes, it's just that I wanted to mention her name because it's adorable).  So...help?  I've found some beauties, but apparently the rest of the shoe shopping world agrees and I can't find them in the right size/color/etc.

Wouldn't these be lovely? 

Or these?  I could wear these a lot, I love the pink heel!

Then there's these...(I'm thinking the lavendar color, since it would match my cute lil' flower girls)

I'm going shopping this weekend, hopefully I'll have some luck.  But if any of you lovely readers have any suggestions, I would LOVE to hear them!
