so i've fallen in love with a pair of stuart weitzman sandals for the wedding. i'm not sure i can bring myself to actually buy them though because of the cost. can anyone suggest an alternate or something similar that is a little cheaper????? i know there are shoe gods out there!!!!!

^^^^ these are them. i don't know why i love them so much but i just do.
the only real requirements i have is that they be flat, or at most a kitten heal, and i would prefer purple but will go with ivory.
thanks for any help that anyone can give. it's driving me nuts........
