When looking for the perfect, form-fitting untucked casual shirt, you must take into account all aspects of the shirt to achieve the perfect fit. Everything from collar height to armholes. Here are some of the essential tips we provided.
Ideally, the collar height and point length are proportional to your size and shape. One that's too big will make a smaller man look like Travolta and one that's too small on a larger guy will emphasize his torso size.
On the backside of your collar, it should rest naturally on, and conform to, the back of your neck. The presence of a collar gap can indicate a shirt that is overall too large or a torso that is too tight.
Sleeves should have about 1 and 1/4 inch extra fabric when pulled away from the arm to provide a fitted appearance while also allowing natural movements without the sleeve becoming noticeably tight.
The sleeve should end right at the divot in out wrist at the very base of your thumb bone.
Contrary to common interpretation, the shoulder seam should fall on the edge of your shoulder bone not the edge of your shoulder muscle.
Higher armholes provide the proper form we're looking for. To test, raise your arms to the side 45 degrees: if the hem of your shirt pulls up more than an inch or so, the armholes are too low.
The button placket should not pucker either at rest or when taking a large breath in. If it does, the shirt is too tight.
The front of the shirt should end halfway down the zipper and the bottom curve of the zipper flap on your jeans.
Shirt Body and Cuffs:
The body of the shirt should be fitted to create a nice silhouette. “Fitted” doesn't just mean slim, larger guys and guys of different shapes need their shirts to be fitted too. A baggy shirt isn't hiding your size and shape, it's just telling everyone that your shirt is too big. For skinnier guys fitted doesn't mean skin tight – for a man of any size the shirt should pull out from the body about 3 inches and no more than 4.
Cuffs should have 1-1.5 inches clearance to allow easy access to your watch.
