Not sure if this is quite what you are looking for, but...
Judeen (Central California dancer) used to wear (and sell) these very cool chiffon harem pants that had a slit up the front that was hemmed with sequins. She had layered chiffon petal skirts that matched them to wear over them, and it was a great look with a two-piece costume.
A long time ago (10+ years) I worked in a place that did not want the dancers to wear harem pants (skirts only), and I was able to get away with wearing these without them knowing/caring. :P Comfy glam--yeah!
I'll see if I can dig up a picture.
Edited to add: She is wearing them in some of the pics on her gallery:
