I'm well into my seventh decade and I've seen a few changes in the world.
I grew up in a fairly warm climate, so hats were not common when I was young. We even played baseball without caps.
When hats were worn, they were usually worn for a reason, like sunshade, warmth, or to keep something out of your hair.
It has been interesting to see the Linus-blanket attachment to hats evolve over the years.
Don't get me wrong- I've worn hats much of my life also. Mainly when I was outside a lot more than I am now. The temp dropped last night to the lowest this winter, and I had to hunt a cap to wear.
In the 60's, the Army abandoned a fairly cool kepi for the fatigue uniform in favor of the most shapeless, nondescript baseball cap ever built. It was horrible. This was just before I went in. It had a rubber brim inside cloth. It was completely impossible to make it retain any kind of stylish shape. It was required in Basic, AIT, and jump school. Even the Marines had a waaaayyyyyyyy better looking fatigue cap.
We had Recon Marines in my class at jump school, and we hated them for having a better hat, even with the pigeon ball stamped on the front.

After training, the first thing we all did was hit the PX and buy a new pair of Corcorans and a decent cap! The crowns could be formed and the brims could be curled.
One had to be a stylish trooper.
Guys who continued to wear the issue hat anywhere but on KP........well, you usually didn't want to hang with a guy like that.
