My friend is getting married in August in an indoor venue. They are having a traditional Muslim wedding and I have no idea what is proper to wear. Obviously I can go by the black tie or black tie optional on the invite (she hasn't chosen yet), but are there any specific do's or don'ts? I want to make sure I am respectful on their big day. They are not Indian, and I can't find any information on Muslim weddings that are not also Indian. Thanks! How would this be for black tie optional? https://www.renttherunway.com/shop/designers/kate_spade_new_york/perfect_era_dress
