I'm very sorry, I have commented without looking back to see how far this thread had advanced. I will leave my comments, but I do realise they are a little out of order. I also agree with all the comments about the camera angle. It is very important to set the camera at waist height.
"The next thing to consider is to take photos of the single garment, worn (with some neutral loose clothing so as not to distract from the garment in question).
The cloth needs to be ironed, and it is very helpful to mark out the drafting lines.
i.e. the centre front, centre back, if it's the pants, it will be the waist, hip and maybe the fold line at front and back. If it's the vest or jacket, the chest and waist lines will be most helpful. You can do this in chalk or careful stitching.
You need to do this against some vertical structure behind, to give context, and to do 4 views: front, right side, back and left side.
I expect no one here minds but it is not necessary to display your identity."
