Banana Republic navy blazer - great condition - size 38

I typically wear a 40 regular. I bought this on my way to a wedding when I forgot my blazer. It is a 38S, but honestly, it didn’t fit me too bad! It has some stretch (2% spandex and 2% elastane) which I think made it work for me. It’s in great shape. I’ve probably worn it 5-10 times. Single vent in the back
