Smart Hat, Woman Smarter!

I cant get over this hat from the day i saw it on the royal wedding!!!!In my opinion Miriam Gonzalez Durantez was by far the most well dressed among the guests,and certainly wore the swellest hat !!!
I' m thinking to make something similar one of this days!It seems quite simple in the making but yet so glamorous!
My only problem is were to find these fine degrade feathers???They look like flamingo feathers but i m not sure...maybe a bit to orangey for flamingo!Hmmmmm...
