This sounds really stupid, but I am still generally vexed as to how people, say, 500 or a thousand years ago managed to get their first outfit.
If you're barely scraping by a living, how can you afford hand made items like clothing, which requires precious natural resources and time to create. Those outfits must have had to last a very long time as well, what did they look like, what was the total flow of the transaction?
How did the weaver get the raw materials? Was it all exchange based? I'll make you a shirt if you give me enough material to make two?
Considering a lot of people didn't own the land or crops they farmed, how did the workers get the money or raw materials to obtain something as simple as a shirt, especially if they were, say, 8 years old.
Anyhow, I'm rambling a bit. It's really easy to take for granted a simple thing like your shirt :)
