There are about 25 of us going abroad for three nights for a hen do.
One of the bridesmaids messaged the group to give us instructions about dress themes. She said we're all to wear bright colours on night two. Another hen suggested all black with only the hen in colour. She was told no, the bride wouldn't want people in black. Bridesmaid reiterated bright colours, and 'banned' anyone from wearing black. Two women have said they are wearing black and that is that, and it's become quite the argument.
Who is BU?
YABU - Everyone should do as BM asks. It won't hurt anyone to wear colour instead of black.
YANBU - Bridesmaid should drop the themes and let people wear whatever they want.
And yes, it's very petty, and no, it isn't that biggest thing any of us have to worry about.
