Here's part 3 of the possible fit problems that you might face!
Always trying to reach up to get something but your shirt keeps getting untucked? This is something for you then.
It is annoying when you raise your arms over your head, your dress shirt comes untucked as it moves up considerably.
This problem can be easily resolved by increasing your dress shirt chest width, making it larger. Alternatively, you may also consider adding 1” to your dress shirt length so it would not be untucked that easily.
