So the morning talk show I sometimes listen to had this bride on whose BM insisted on buying a dress two sizes too small because she wanted to use it as motivation to lose weight. So this bride was thinking about going behind her back to somehow switch the sizes so the "normal" size was ordered instead. She was hoping that the bridal salon would back her up to avoid a disaster when the BM couldn't fit into the smaller size. What do you guys think about this? What would you do if you were in her situation?
