A story did the rounds a while back, about Stella McCartney designing a necklace with a leg pendant in order to piss off her then stepmother, the one-legged Heather Mills. However, I'm not convinced that the whole thing wasn't a bunch of hooey, given that I've never been able to find an actual photo of the said necklace.
Anyway, I'm using this bit of 'news' as an excuse to showcase several necklaces that have body-bits on them.
First up a leg necklace that actually does exist:
From Caja Jewelry
Next, this mustache I've been jonesing for ages (in my book mustaches count as a 'body bit'.)
And the pièce de résistance:
From Vivienne Westwood, of course.
