1970s Kemington Denim Blazer Jacket

Kemington Express denim blazer || 21” ptp, 19.5” waist, 28” long Most likely 1970s. I’m not 100% sure it’s from the 70s, but from my research that’s what I’m thinking. I’m not an expert so keep that in mind :) The tag is worn out and I can’t read it, but the buttons show the brand. One of these is on Etsy right now for $75! Super cool.
