SHE'S HERE! My Diane Messenger in Châtaignier has arrived! I'll be posting more as I use the bag, but wanted to provide my initial experience and photos in case it's helpful for anyone.
ORDER & DELIVERY PROCESS:
I ordered 27 Dec 2023. At time of ordering, the website stated to expect a 3-6 month wait. I received my bag 21 Apr 2024, so roughly 4 months.
The bag got held up at customs in the US. DHL had to reach out to me for my SSN and a supporting IRS document for SSN verification in order to release the bag. JD customer service also reached out to me directly to know of this DHL request (in case I had missed it) and confirmed that it was legitimate. After researching and confirming on my own that indeed Customs needs your SSN for any imports over $2500 for tax purposes, and confirming with DHL directly that this was indeed their standard DHL process, I provided my information. I did not have to pay any additional duties or fees because it was already incorporated in my purchase when I bought the bag.
JD also reached out as soon as I had received my bag to ask me how delivery went and if the bag met my expectations.
UNBOXING:
If you've seen Lula's video on YouTube on her unboxing, mine was pretty similar - only differences were that my brown shipment box was way closer in size to the Joseph duclos box (likely nearly the same size) and I did not get the ceramic ornament she did (but I wasn't interested in that anyway).
I attached photos of what the bag looked like fresh from the box.
MEASUREMENTS:
I have also included photos with measuring tape for those of us who like to make prototype bags before we buy

I would say the bag is 11 inches wide, 7 inches tall, and 2.5 inches deep on the side and allllmost 2.75 inches wide on the bottom. I couldn't snap a good photo of measuring the strap at its max, but I would say it's 47 inches if you measure from tip of the hardware clip to the end of the other clip, but you also want to include the rings you clip the strap to on the bag, so I would use a measurement of 47.5 inches to estimate what the max strap would feel like on your body.
The strap set at the longest length is PERFECT for crossbody for me. The top of the bag hits just at the same point as the top of my jeans. I was a bit worried since I'm a huskier gal (size 10-12) and thus I can't typically trust that a crossbody on a size 4 will hit the same way on me.
GENERAL IMPRESSION:
Yup, this bag scratches easily - and I'm not mad about it. It buffs out relatively easy with your fingers if you really care about it, but I feel like the stratches are going to be part of the bag's character and charm for me. It's the kind of leather that I wanted. The smell is divine, the structure is solid, and the color is better in person than I hoped. It is sort of chameleon in a way - most of the time it is the darker color that I was hoping it would be, but in direct sunlight could be seen as a bit brighter of a brown. I'm really excited for the leather to patina and color over time.
All in all, quite pleased!
