Hiya
Was umming and aahing about posting this here or in the chat section but AIBU is where the other threads were posted. IYKYK. I have had the (dis)pleasure of reading all 80 pages.
I'm the bride and I can confirm my SIL did turn up wearing the dress to the wedding. My best friend/MoH waited until after the wedding to show me the threads since some of the posts were a bit horrid tbh and she was so right I didn't need to see that before the wedding. She organised a post wedding girls night for me and the rest of our friends group who came to the wedding and that really was such a brilliant and surprisingly entertaining way to read through and digest it all with a few glasses of wine, some music and lots of love and support.
The consensus after last night's wine & whine is that I should keep shtum about the dress and the threads to MIL/SIL in person and that it would be better to create this thread and who knows they might come across it
Another idea that was floated last night was photoshopping the wedding photos with SIL in them to make her dress pink or yellow. If this is an awful idea we blame the wine!!
