How often do you replace work clothes?

I’ve been running the numbers and thought I’d ask the community

So I own two shirts and a pair of pants that I wear to work all week. between the time I bought them I must’ve worn the shirts at least 108 times and the pants 220 times. The pants are getting a little frayed at the “cuffs” and the shirts seem fine. the shoes already have holes but still do the job. So when do I officially move on from these clothes without being wasteful? What is your threshold where a garment is not worth fixing?
