I use a pattern from folkwear.com for the hakama. It's a great pattern because before I bought it, I had no clue about hakama, but now, I can turn out hakama in about a day. I got a few pictures in my galleries of me and others in the hakama.
As for the top, I made one for myself as Soi Fon. I just modified a halter top pattern to make the white one, then sorta free-handed the black one since it doesn't cover the back. It was an odd process but it worked out in the end.
Not the best reference shots, but here are a few of my Soi Fon as well as a few other friends in the hakama I made: http://www.cosplay.com/gallery/90502/
