Similar sunglasses?

Hi!

I was browsing some photos from one of the fashion weeks and stumbled across this photo (http://imgur.com/jNsu5lD) and fell in love with the sunglasses!

Does anyone know what these sunglasses are, or a similar pair?

I'm specifically looking for a tortoise-shell frame, and with lenses in that same rounded fashion. Similar to the Lemtosh's by Moscot. Also I'm in Europe, so I'd prefer international sites, but I can always look through Ebay if I have a style to look for :)

Thanks in advance! It's much appreciated!
