Ayu wore a poncho-thing from Jen's Pirate Booty in Sweet. I'm not sure if this is the one... she also wore AULA AILA, but I can't find the specific dress.
The poncho is nearly 200 dollars~ haha.
There were also a few Dan Winston hats worn. I can't find the white dresses though. The one in the photo up there is from NINE (
http://e-nine.com/)
400USD and 130USD or so respectively.

The flower hat is a "maybe" since the styling of the flowers is rather different, haha.
