If you don't want to buy a hakama, you can easily sew them yourself. I already posted my pattern here (search for "home made hakama").It's not perfect (I'm still working on a koshiita solution) but works. They are easier made than you might think. And, you can choose color and pattern...I just made one with two different shades of blue (navy/turquoise) and I'm planning on a red/black and a dark violet one...
