Yuna, Rikku and Paine's hats worn with their Black Mage dressphere in the Ps2 game: Final Fantasy X-2
I've never actually done this sort of model before, in terms of the fact, the hats were attached to the heads of each model. I had to remove everything else just to get the hats and even then, they're not perfect. I apologize for that.
For Rikku's hat there is a black rim-like part of the inner hat. This is from the head-band on Rikku's head (I believe). I could not remove that without effecting the rest of the hat but you may be able to make it work depending on what you use the hat for.
Unfortunatly, only parts of each hat could be smoothed out with doubles removed in Blender. So if you can fix that, feel free.
There are no bones for the models either.
Culling options are required for Rikku's hat and (possibly, depending on your preference) Paine's. Yuna's however is not needed but if you wish to use the options for all 3, you can.
The hats are as follows according to the preview image (with culling options on): Top left- Yuna Top right - Rikku Bottom center - Paine
