You know that weird habit the Japanese have of making plushie animals that are dressed up like other animals? Hello Kitty pretending to be a panda, anyone? Well, my friend has this seal. It's dressed as... well, what she thought was a seal, and recently found out was actually a bear. But we all thought it was much cooler as a seal dressed as a seal.
I have a point here, I promise. And it's even related to fashion. "Trompe l'oeil" is the term we use for visual illusion. Theoretically, this is what Mary Katrantzou is doing. Except is it still an illusion if she's drawn a shoe, on a shoe? You think you're looking at a shoe, and guess what, it's really a shoe! Which, if you follow my whole seal-as-a-seal analogy, makes it really cool.
Although, the dresses below -- dresses dressed as shoes -- are pretty damn cool too.
