Does anyone know where I can find sungles like these?

I was wondering the same thing about a pair of Kate Spades a few months ago. I e-mailed the picture to info@replacementlenpress.com and they told me exactly what frames they were, and what they could sell them to me for (they sell at wholesale prices). They specialize in the prescription lenses, so that's what their website is all about, but they actually do sell frames. And at very good prices, too. Good luck ;)
