Pricey Clothes Worth the Money?

With black Friday deals coming up, I've been scoping out the most recommended clothes for the PCT. I consider myself a relatively frugal person, but I'm willing to pay a decent amount on clothes since I will be spending all day everyday wearing them. I wouldn't mind spending a little more for items if I will be able to use them after the trail, but if it's guaranteed that they won't outlast the trail, I may go for more of a middle to low price range.

On average how long does your gear last? Sorry in advance if I've missed this thread pass by already.

Thanks!!
