As a tangent,
A good system to keep ppe/ uniform costs in check is to ISSUE them their gear. They are responsible to turn all the gear back in at the end of employment. Whenever they wear something out, they simply turn it in for replacement. If they don't keep track of their gear and lose it, they pay for it. Some fudge factor in it. Give them a memento shirt/hoodie as appropriate.
When I worked for Americorps/ Nevada Conservation Corps, I came up with idea. This way the irresponsible people would have to spend their own money for losing things, and the responsible people could always trade in for replacements, no questions asked. There would be money to replace worn out stuff, not the new stuff the same person would lose all the time.
Once that became the policy, loss went WAY WAY down. Nobody ever was Actually asked to pay/ had deducted from their stipend (and I doubt that we could have deducted from the living stipend, some people were staff on salary, such as myself). There was always money for replacement gear, and people were not wasting time finding uniforms/ ppe for irresponsible people.
Luckily, I've not had to deal with chronic losers (well, one chronic user, loser, that only lasted one week and didn't understand he was getting fired. One of two first guys I hired when I was desperate and booked job early, early on and needed bodies).
Magic marker/ sharpie people's initials on everything. People often know their own stuff, but its easy for a co-worker (and a manager) to know who left something around, and who should get it back.
Issuing an employee their gear with a pricelist can help with this, too.
Each shirt $13.75
Hoodie $30
Chaps $60
Helmet/ hardhat xx
glasses
etc etc
work pants
rain gear
Total cost of gear issued $xxx.xx
I understand that I'm responsible for caring for and return this equipment back to the company at the end of employment and will return it before receiving my last paycheck. I will have any missing gear deducted from my paycheck.

The threat of hitting someone in the pocket book, and explaining that this allow you to properly outfit everyone seems to work.
Positive consequences follow responsibility, and negative consequences follow irresponsibility. Not wasting company money leaves more money for raises and bonuses.
