This is an interesting subject for me. Putting on coveralls involves taking my boots off, which needs sitting down and bending forward. Back and shoulder problems make this painful and slow. Struggling without taking off boots is worse, when the coverall legs get hung up on the boots.
I hate changing clothes, so what I put on in the morning after a shower is what I go out in at night and take off before I go to bed - funerals and weddings excepted!
My saving trick is to have 1 litre cans of Shellite, (X55 solvent, lighter fluid or white gas are the same thing here) and a large roll of paper towels in the workshop, my office, laboratory and home laundry (my hobby workshop is in my factory building, 7 minutes by car from my house). Each time I get grease on my jeans or shirt I get it off with this "dry-cleaner fluid" which evaporates in seconds.
My clothes ethic is compounded by the nature of my factory where we manufacture and use sticky resins constantly, so a can of acetone sits next to each can of X55 for a similar purpose. And sometimes a wipe with a mix of both solvents (plus meths too if called for) is needed for unidentifiable stains like gasket cement, paints etc.
So I manage to keep my jeans and shirts reasonable until they wear out.
For dirty jobs like changing a gearbox, I put on a hat and brown dust coat. And maybe a filthy shirt and ripped jeans for really mucky jobs like using liquid cutting and polishing compound on a paint polishing mop.
I can no longer roll under a car due to old back injuries and arthritic shoulders, so coveralls are not essential - all work is done using a 4-post hoist.
This is a long answer, but the OP's question made me think about what I do and how it evolved over the years as I became less mobile.
My wife loves to change her clothes and looks different several times a day. Me, I hate the time effort, extra washing, bending, etc that changing clothes involves.
Man, I have turned into a crusty, inflexible, grumpy old Git in the last few years!
