Those are really nice, especially the first one, but I know everyone doesn’t have $1300-$1500 to spend on a jacket. After searching, I found about 4-5 similar jackets on eBay. And though you may be reading this one month after it was written I’m sure that similar jackets are still on eBay.
I also found some great simple military style jackets that would make for great staples in any man’s fall wardrobes (plus they’re perfectly priced):
Hope that helps! Feel free to leave suggestions on where to specifically find more marching band jackets.
