First, the shoulder seam should sit where arm meets shoulder (without hanging past that point).

The shoulders shouldn’t be so narrow that crossing your arms across your chest creates tightness or pulling.

Second, the collar should button comfortably without being too tight. You should be able to fit one finger comfortably between your neck and collar.

Since you won’t be wearing a tie with your flannel shirt, you probably won’t be buttoning the top button, so it’s okay if it’s a little bit too tight or loose.

Third, the bottom of your shirt shouldn’t go past bottom of your pants fly when worn untucked. If it hits somewhere around mid-fly, it’s the perfect length.

If your belly is exposed when you raise your arms up over your head, your flannel shirt might be too short.

Fourth, the sleeves should hit your wrist without going past it. They should stop on top of or just past your wrist bone.

A bit too long is usually better than a bit too short, unless you like the cropped look.

Remember: these are just guidelines, so don’t get too hung up the fit

What Makes a Flannel Shirt Casual?

Besides fit, there are some other little details that make a casual button different than a dress shirt.

First, the hem is straight or slightly curved. There are no deep “wings” like you see on dress shirts that are meant to be worn tucked in.

Second, the sleeve cuffs are soft and pliable. There’s no stiff interfacing like you see in dress shirts that are mean to be worn underneath a suit jacket or sport coat.
