Men’s slim fit sport coat / jacket / blazer navy blue and white stripe 1670

Hi! This is a fun blue and white striped medium or 40R jacket I bought online from the Bay. Rarely worn and in like new condition. I’m 5’10” and 185 lbs and a 40R. This jacket is a slim fit . It fits me great in the shoulders but is tight in the tummy. If you’re a 40R and want it to button up then you’re going to need a narrower waist than me!
