Classic Checked Blazer S Vintage Boxy Retro

This is a classic blazer inspired by men’s tailoring that has a longer and more boxy cut than women’s blazers normally would. I’m pretty sure that it is vintage, but I’m not 100% sure. It feels like there may be some wool content, but the tag is worn and all I can see is rayon and polyester mentioned. It is in very good, pre-owned condition. The size tag is missing, but I think it’s in the S or possibly M size range. Bust - 38 Waist - 32 Length - 27 1/2 Sleeves - 24
