I made this war. XD
Well. I appreciate all your comments. I still have no idea yet about the dress code since my graduation is far away. It will be two months from now. I am just wondering what to wear, as so as to be prepared. Also, I think that my university would allow us to be "liberal" in choosing what are dresses will be and I think that would really complement my degree which is related to Humanities.
I also like the idea on how johnnvw cited some sources. Thank you for that! I am really happy getting ideas from all of you and I'd be happier if we discuss this in a non-militant way. :P
