I think it's a Soft and Chain flap. I don't live near a boutique, so can't you with where one might be available.
Ultimate soft & chain flap - NM in SF & Troy both have the royal blue color, between $2195-2225.
See under shopping threads : Live from San Francisco..NM STOCK Update & Where can I find these blue flaps?
I love the color but find the chain is a bit too short.
I think I saw one at Saks at 59th St in Manhattan when I was there on Monday. Sorry I'm not sure because I was at the Chanel boutique and BG that day too. Saks is having their EGC event today so if they have it you can also get a gift card. The number is 212-940-4347. Good luck!!
This soft and chain flap is HOT!! Wow!
