1. Prada -- if I go off of percentage of total shoe volume! I have a lot of Prada
2. YSL -- for sexy, even the "work" shoes
3. Manolo Blahnik -- classic styles, some comfy, some painful but beautiful!
4. Lanvin -- for the flats
5. Rupert Sanderson -- elegant, ladylike
I stay away from CL simply because he is SO popular, though I think some of the styles are lovely. Generally I feel he is about $200 more than he should be for a pair of shoes.
I also like Chloe for the edginess factor, and Thierry Rabotin for the comfort.
