Hmm, I thought I posted a reply here but it's disappeared!
What I was saying was that "backlighting," a stage or a situation where there is light coming from behind the performer, will make skirts look sheer that were never sheer before!
Sheer harems, underskirts, etc. will all help in that situation. For the record, I don't hate harem pants, but if I posted that over on that other thread, I would be a blasphemer!
(Lovin' the smileys, hehe)
