My fiancé's sister is getting married in May and her bachelorette party is at the end of March. Her sister (MOH) thinks it's a great idea to "make" her wear a skimpy white halter dress from high school -- which she graduated 7 years ago -- that she probably won't fit it anymore because it's "got good memories (for the MOH.)" Everyone else in the bridal party has told MOH dozens of times that it's a BAD idea, and she's not listening, and going ahead with her plan which is completely different from anyone else's…. how much interference should we be running at this point? Should I just take the bride shopping for an outfit for the party? Am I the only person that thinks this is completely bizarre?
