Your dress shirts elbows seem to tear after a while.
Although your dress shirts keep having tears around the elbows, it is not necessarily a sign of a poorly made dress shirt or a cheap fabric used.
In fact, the problem usually occurs due to an incorrect fit. A fit adjustment can reduce the occurrence of the problem.
You may want to consider widening the sleeve width (bicep measurement) to provide more room around the elbows, lengthen the sleeve length to have more allowance for movements, or choose a thicker dress shirt fabric.
