The linked article recommends the following clothing purchase strategy,
The average American household has a median annual income of approximately $50,000. If it spends 3% of their income on clothing, they’ll have $1,500 a year, or $125 per month to spend. Instead of buying five fast-fashion, low-quality items costing $25 each, they could invest in one or two quality items at a higher price point ($125 or $63 respectively).
I’m not confident in my ability to determine if a $125 clothing item is really has 5x the quality as the $25 item. My suspicion is the $125 clothing item is maybe 2 or 3 times the quality of the $25 item.
My solution to the clothing problem was to find a decent black cotton t-shirt I liked (this one) and bought 30 of them back in 2009, which I pretty much wear for everything. Of the original 30, about 10 are no longer wearable. Not sure if that means they are high or low quality, or even how I would even begin to evaluate that (what is the average lifespan of a low vs. average vs. high quality cotton t-shirt??)
