I texted my SA and asked him TWICE in text when is next price increase. He never responded back. Lol. However someone on this purseforum stated it will be in Jan of next year but I'm not sure how she found that out. Regarding my mitzvah, no I did not purchase it at the same time as the cost of the bag was enough! Lol. However, I did it myself and I did the braiding technique. The mitzvah is long, and I don't care for 2 long "tails" hanging down the front which is why I do it this way. All you do is bring the mitzvah to either end of your top handle. Drape the mitzvah evenly divided in length over the top handle and position the mitzvah at the base of the handle, so you have one tail end of the mitzvah draping behind the bag and the other end draping in front of the bag. Then just take both ends and just "braid" both ends crossing over and beneath the top handle making sure the mitzvah is smooth and not bunched up. Keep doing this technique until you reach the other end of the top handle and tie the ends together. Thats it! It holds up pretty well too and doesn't loosen up too much as you use the bag. I hope I explained that well enough so you're able to visualize it.
oh, to answer you, yes Dior will put it on for you as well.
