Being a PR major, I have a great answer to this question.
I would wear the other orgs nalia. However, during the credits, I would have the show write something like the following:
Chickenlittle is a devoted and active member of DST. She portrayed the role of a member of ZPhiB solely for the purposes of this film and in the name of true greek love. Blah, Blah, Blah
And also, I would get written permission from the orgs national headquarters to ensure that there are no legal ramifications of this part.
No problems, no conflicts of interest and I get my money. But, without these things being done, no I would not do it. My credibility as an actress and a member of DST would be on the line. NO AMOUNT OF MONEY IS WORTH YOUR CREDIBILITY. Always remember that.
By playing the part, it will show my versatility as an actress also.
I'm smart. I know it. I have the GPA to show it.
