@TMMC1 its very very clear you've never worked with vulnerable people. I have, as a police officer in uniform and plain clothes. I've come home covered in vomit, blood - sometimes my own but usually someone else's, urine, shit, fleas, ticks, mud and all sorts of dirt and dust.
The worst day like that was after working with a body which hadn't been found for a very long time. I walked into the shower still in my body armour and uniform that day then everything I wore bar the body armour and my boots had to be thrown in the bin. The armour cover took five boil washes with every chemical I could find to take the smell out. The armour itself was wiped down with alcohol wipes for about an hour.
In outreach type roles (whether police, social work, probation, housing, charity etc) you need clothes to be washable. Highly washable at boil wash temperatures, repeatedly.
You need shoes to be sturdy enough to avoid needle stick injuries from hidden needles. That doesn't help you when they are in the sofa you just sat on, or in the kids bed you just checked, but you can't avoid everything....
You need to be able to leg it if things don't go as planned due to a client's mental health, drug and alcohol addictions, or just plain anger because you aren't giving them what they want.
Clothes tell a story. To someone on the bones of their arse, a nice lady in fancy expensive clothes and jewellery will be a subject of derision not inspiration. If the same nice lady rocks up in jeans, trainers and a hoodie or removes a huge and immediate barrier.
