For your battle dress since it is likely to get messy, you might want to try the SWK Thrifty line, they have the Black Watch. For $30 you get yourself pretty close to a real kilt in looks without worrying what happens to it.

For your dressy look check out the Pics threads.. You'll find plenty pics of XMTS members in dressy kit. You shuld get some good ideas from there.
