No, you're a muscular guy (big drop) and you're going to look like a moron in your little tight blazer not some rock god. If you're merely asking if you can fit it well then, yeah, go with your shoulders and wear a 52. Don't forget SLP is built for columnar dudes (slim but with a small drop, like an "I") so they cut isn't for you, you'd be better off in something like Dolce and they make those kind of dinner jackets, maybe Lanvin with some alterations would also be more forgiving.
well said. He can fit into the jacket but it will not look good.
Some of Lanvin Fully Canvassed Dinner Jackets fits are slim which wider shoulders compare to their other blazers.
