I think it's this one: http://custom.luxire.com/products/grandi_amazing_08561_09105
With their standard BD collar, which actually had a nice roll not really seen in the photo.
Not positive about the fabric since it's all kind of an blur at this point...
Gorgeous fabric... in both the link and your photo, so I'll assume they are the same. I've got a credit from Luxire burning a hole in my pocket, I might just put it towards the same shirt.
