You are talking about the hedonic adjustments which is a hugely studied part of inflation calculations. For any way to calculate broad inflation you’ll find products that inflated more than the calculation (and less).
Your own example is an interesting one because a) it’s very hard to compare clothing by objective quality b) you’re changing the goal posts. I’ve found a carhart product that nearly exactly matches your specification and msrp’s for $40. I’ve seen discounters selling it for $25. Which is getting very close to your specific target.
