Ahhh Haaa!! Found it.

I looked in the readme, but it doesn't address redistribution, which means "no".

But I did find the website and it's also closed:   http://lafiesta.sakura.ne.jp/

There ia an email address in the readme file. Perhaps you can write to Rose and ask if you can acquire the shirt textures.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
