I've been trying to work out what the current shoe trend reminds me of. I pondered why only very young, coltish women look good in them. Then I figured it out - hoofs! Except of course, that's already been figured out... and if you look at the bottom right image, shoes exactly like hoofs are now being designed.
The origin of fashion elements is a very cool study. I wonder how many women - who wear those big scarfs wrapped around their necks year round - realize that they're burka-inspired?
