The situation when jeans will contact the back, you can not call pleasant. I would like to put them in a figure, without using barbaric launches, shifting pocket and visually increasing waist. There is an exit! An extremely simple way to make jeans "stick" to the back exists.
The problem is easy to cope with a small piece of thick gum. The main thing is to sew it in a special way.
First you need to fix the gum in the center, and then tighten and shoot each of the sides to the belt towards the belt from the center so as not to hook a belt loop. The place of fixation of the gum also fix the line.
Pants are now sitting according to the figure, and a few minutes went to work.
