In addition to pre patching- reinforcing clothes. There were undergarments and over garments made to take the wear and tear so clothes lasted longer.
From under arm pads to short pants ( loose longer undergarments) under the pants.
Sewn onto some pants would be cuffs of contasting more durable fabric.
On shirts cuffs , collars, anywhere buttons were and pockets were reinforced and or made of contasting or coordinating thicker fabric.
Overgarments like aprons ( from cotton to leather depending the chore.)
Kneepads, fire resistant fabrics in areas you might get to hot hands and croches were the most covered ( cooking, metal work)
And even chemical deterants like waterproofing heavy cotton ( ducting).
Modern fabrics and clothes and even modern-day fabrics aren't made even simular at least right off the shelf at walmart or joanns.
