Vintage Woman's Button up Blazer Red, White & Blue Plaid with two front pockets

Vintage Woman's Button up Blazer Red, White & Blue Plaid with two front pockets I am not able to read the tag so do not know the brand. Material is very light weight. Used good condition. No stains, holes or tears. This is my mothers blazer she has owned it for quite some time she is a Medium Petite size and it is too small for her. I would say this is a size small See measurements in photos
