The proposed, er… demanded outfits are so ghastly and yet hilariously expensive. Not to mention impractical for a big Hawaii beach dance number! But don’t worry, those who decide NOT to participate can do volunteer janitorial duties post reception!
The worst wedding behavior I ever encountered was actually from the MOH for a wedding in which I was a bridesmaid. She wanted to have the bridal shower at a literal castle that was vastly more upscale than the actual wedding venue, and then freaked the hell out at the bridal party when we all refused to fork over $1200 each on her Disney Princess bridal shower theme.
After reading this, though, that seems comparatively sane. WTF!!!
