Takarazuka Graduation Day

Normally when we graduate from university in Japan, female students wear Hakama like this,
but look at the following site, Takaraduka Revue Company's graduation day seems a bit different!

Takarazuka is well-known to be women's only revue company where women do both male part and female part.  Those who do male part lives like a man and female role lives more like women.　I haven't seen any woman wearing this type of black crested kimono but they are so beautiful!
