The whole knight set is three crafts you already know. This cuirass comes from the road sign jacket, the skirt plates from the kilt, and the knight helmet from the coffee can helmet. None has a blueprint of its own; owning the skins turns plain road sign gear into plate when you craft it.
So the bill is the jacket's: leather, two road signs and two sewing kits at a Level 2 bench, and it wears down exactly like the jacket. The choice is looks.
Count kits before a medieval raid. One player in the full set needs five sewing kits: two each for chest and legs, one for the helmet. That number, not the skin, decides how many of you march out in steel.
