Vintage blue and yellow plaid wool jacket

Fabulous double breasted yellow and blue plaid jacket. Has no label-might be one-of-a-kind piece. Beautiful silky purple lining. The slightly rounded collar and fabric covered buttons make me think this might be from the 60s? not sure of the fiber content, it's a medium weight woven fabric that feels like wool or wool blend. In excellent condition; no visible flaws. Note that this jacket does not have shoulder padding! Garment measurements when laid flat are 20" width, 26" length, and 23" sleeve length. For fit reference, my measurements are 35" bust/27" waist and 5'4" tall. Would say this jacket fits like a size 8-10.
