The Wall Street Journal sizes up ‘slim’ shirts:
But slim fits — called everything from tailored to modern fits by manufacturers — aren’t just for slim guys. Some are cut roomier on top to accommodate men who are muscular — or just bigger — in the chest. We compared 10 slim-fit shirts with 16-inch necks and found that chest measurements varied by as much as five inches. Some tapered from wide shoulders to narrow waists, while others had straighter, boxier cuts, including some with relatively wide waists. Some could be worn only by truly thin guys.
Their Best for Big Chest and Narrow Waist:
Arrow’s fitted shirt, with a 49-inch chest, is the widest on top and among the narrowest at the waist, where it measures 42 inches.
For a 16-inch neck, a 49-inch chest is pretty big — but so is a 42-inch waist.
By ancient Greek ideals, a 16-inch neck would go with a 43-inch chest and a 30-inch waist.
