Men's Italian leather jacket - Size Small

I purchased this men's leather jacket while in Florence, Italy in 2021 from the Scuola del Cuoio (the Leather School of Florence). The school is a prestigious, longtime leather school offering bags, belts & jackets handcrafted by artisans on site. The leather is very smooth and luxurious. Unfortunately, I should have bought a larger size as it is just a little too tight.... rarely worn and in perfect condition. FYI, I am 5'8" and 165 lb. ....So if you're slightly smaller, this jacket should fit perfectly! Paid 600 Euros....$720
