SameTo me the army jacket thing is from the Vietnam War counter culture days, a style that never seemed to really go away. Lots of hippy and folk musicians used to wear it back in the 60s and 70s.
I have never been up on current fashion in any way. I got an military surplus jacket many years ago (before I served in the military and wore one for real as part of a uniform) and I've always worn it as a casual jacket just because it's really comfortable, has lots of pockets, and you can wear more layers under it when it gets colder out. It's the old style, olive green instead of camo, so it comes off less rednecky. Later when I grew my hair back out and started playing music again people acted like I must wear the jack because I'm in their club. I don't. I wear it because I like it and I'm not in anybody's club, thank you very much. I have a professional day job and am way more square than you might think at first glance. But I'm always down to jam with you if you're cool and on the same wavelength music-wise.
Also I wear black pants because they go with any color shirt and I suck at fashion, like I said.
Black pants fit with everything
The army jacket is comfortable and can add layers depending on weather.
Though here in Quebec it’s definitely not for our cold
Main feature is the pockets.
