Shoe shopping in London

If you remember back in March I {thought} I found my heels for the big day...however they were purchased before I had found my dress and the reality is they don't exactly match with the style of my dress. So, I'm back to heel hunting!
Recently in London I went to Harrods in hopes of finding heels...but either heels are way too high {what's up with that?} or too low as in "only Aunt Hilda would buy that low of a kitten heel". And of course way to expense, seriously who buys heels for close to $1000? Not a bride on a budget, yes even one that has gone above her initial estimate.

Casadei heels

Christian Louboutin

Rene Caovilla (OMG! The soles of these heels are gorgeous, sparkly grey!)

Christian Dior (these would be perfect but they are way too high)

the Dior booties are fabulous but wouldn't exactly match my gown's style

I think these Valentino might be it!! Rather find them in Toronto.

Any suggestions?
