Next, user your favorite acrylic paint to give some color to the belts. This is supposed to be a quick job, so I don't even bother airbrushing them. I like to use Vallejo paints here because they dry fast and remain relatively flexible while still not fully cured.

I used this method in the seat of my Hasegawa Dewoitine D.520 in 1/72, along with an improved kit's seat. I went a bit further and marked some grommets using a sharp pencil (I could have added some paint wash, too). The sticking side allow you to pose the belts anyway you want as you go. I usually apply small beads of super glue to anchor the invisible ends of the belts, just in case. The result is very convincing:
