I'm one of those people who if I top up the oil in a vehicle I look like I've done a complete engine strip down.

I put my chicken/animal clothes on to go to town. I travel on public transport accross the city to get to the chickens and allotments. I look like a street living person most days. Every nutter at the bus stops and train stations tries to talk to me. I've had people try to give me money and people from the salvation army almost try to wrestle me into a night shelter.
My allotment/chicken clothes are either waterproofs or overalls. Sometimes I think I've got enough layers on to absorb the shock from a fall from a second story building.

I wash my hands and boots when leaving the allotments and my hands when I get home after stripping the top layer off.
When I was in Catalonia I spent most of my day outside tending to one creature or another. It just wasn't practical to be changing and washing between tasks.
