I've been toying with the idea of a jacket project as well. I'm nervous about fit (assuming I'd be dropping ~300 for a jacket I can't try on ahead of time is a bit daunting). Thank you for posting. It turned out really well.
I just leave all the measurement stuff blank and say "same dimensions as order ### with the following changes _____" Also, you should note that your previous order is "shape only". So if you have special features, like cuffs, lining, pockets, zippers, buttons, etc, you need to repeat that explicitly for future orders if you want those features included.
I had really good luck with a handful of safety pins and a ruler. Pin the shirt back in spots where you want to reduce fabric. Measure how much you removed by pinning it back, and exactly where at (it helps to start with the places Luxire does their standard measurements at), and send the changes to Luxire. For what it's worth, I think your initial fit is pretty close, and I'm not sure your body type is as unique or as difficult as you think. I think the pin and measure...
How does a person avoid placket buckling????? It drives me completely nuts and I've received nearly no constructive feedback when I've asked in the past about it. I have a very slim frame and my shirt selections fall into 2 catagories: Crazy placket buckling or Wearing a tent. EDIT, just noticed you can see the placket buckled on my shirt in my avatar pic
It worked for me on an item that wasn't previously in my dreambox and it applied free shipping to my entire order (which wasn't all in my dreambox).
I snagged a hella bargin, about 75% off retail on some sweaters I really wanted. And free shipping to boot.
