My FI and I were invited to a Muslim wedding (FI's friend's sister), and the family of the bride is very traditional (arranged marriages, parties where men and women are always segregated at their home, etc). I have already been told that wearing red is a bad idea since no one wants to upstage the bride, but I'm having concerns about other parts of the attire.
Is black an acceptable color in Muslim tradition? Would I need to wear something longer than knee-length? What about bare arms, since my cocktail dresses are all sleeveless? I asked FI to ask his friend about this, but he thinks I'm being goofy and worrying too much. I'm not opposed to going out and getting a new dress to wear (I'm guessing pants are out) if that would be easier than wearing 4 different layers to try and make what I already have acceptable.
