I was going to say exactly what Pete said.
I bought Downy Unstoppables a few years ago because, (a) let's face it, I'm curious about laundry stuff, (b) because I wanted to get P&G etc the idea that their *best* bet is to sell only *one* kind of laundry detergent, which is unscented, and let us play with scent some other way, say, fabric softener and/or something to shake into the wash cycle. I *still* have them, because it doesn't take much to last all week and I prefer just a tiny bit of scent, so I use much less than they think I should.
Whoever is currently producing All and Snuggle also has a line of scent pods and now even a "squeezable" thing that promises 100 days of "freshness". LOL.
In any case, I'm not sure of the situation in your wife's job, or what the uniforms are for (very different uses for say, nurses, firefighters, waiters, bank tellers etc). A person sitting in a climate controlled place doing no physical work, more or less like a bank teller, might get away with wearing the same uniform 2 or 3 days. I am under the impression that people on their feet walking all day long, like waiters and nurses will probably be better off wearing the uniform for a day and cleaning it.
I would like also to point out that there is wear and there is *wear*. People sweating on the fabrics will deposit salts and other things that abrade the fabrics. In fact, specialists say that, for example, people who get home and walk barefoot on their carpets get the carpets worn out much faster than people who wear slippers.
There's a good tipping point for everything -- for example, jeans look more worn out faster if they are washed once a week than if they are washed every 2-3 days (assuming, for the sake of the argument they're worn every day).
For what's worth.
