Bride had maids that ranged in size from 14 to 26, all with big 'ol boobs. Despite this, she had us mail order dresses that no one could try on ahead of time and couldn't be worn with bras (any, not even strapless). The dress arrived, I tried it on and dutifully sent her a picture of me in it, even though it wasn't a pretty site. So we're at the destination wedding and us maids all suit up and everyone looks absolutely embarrassing. The dresses tugged and pulled and created rolls where there usually were none, plus one riiiiiiiped open all the way down the back moments before the ceremony. Due to boning and fabric with zero give, the dresses were physically painful to wear and we looked terrible to the point of us all being panicked about ruining her pictures.
Bride heads off to a 3 week honeymoon planning to return a few days before her large local reception. Us maids all got together to pen an email where we profusely apologized for looking so terrible in the dresses, apologized for putting her in this position, and expressed our concern that we ruined her wedding pictures. We offered to all buy new dresses within her wedding colors, would pay for them without complaint, and assured they'd all match her vision. Bride responded that we were immensely selfish for interrupting her honeymoon, that we all should have lost weight prior to her wedding (ya know, because she got a boob job and tummy tuck. seriously) and that she "told everyone about the dresses" and would be so embarrassed if we showed up wearing something different.
In the years since, the Bride talks to zero of her four bridesmaids. I think the wedding was the turning point where we all realized how she treated people.
