Your sleeves should be long enough so that the cuffs do not ride up your wrist when you move your arm.  The cuffs of the shirt should also not go past the first inch of your hand.  You can use a ruler to measure whether there is too much extra sleeve length, and how much the shirt needs to be taken in. They should not hang over your hand. You should not be able to slip into shirt sleeves without first undoing buttons on the cuff.  Run two fingers underneath the cuffs.  If two fingers can fit comfortably under the cuff, then they are too large. They should be well-placed, with no gaping holes exposing your chest.  Slip your four fingers and thump between each button.  If your hand slides through, the buttons are too far apart. Breath in and out naturally, to see whether or not there is enough loose fabric.  Keep your legs straight, as you slowly move your upper body forwards and backwards.  If the shirt is cutting at your chest, you will want a shirt with a tad bit more fabric. Check that shirt tails do not come out of your pants.  Bend your upper body sideways and backwards.  If your shirt slips out of your pants, this can be embarrassing in the future.  Also make sure to check your belt, and make sure it is tight enough to hold your shirt in. You should be able to slide two or three fingers between your neck and collar.  Slide them from side to side, all the way around your neck.  Make sure that while wearing your breathing is not becoming elevated.  You will want to be able to breathe naturally and comfortably.
اثن ذراعك بينما تقف مستقيمًا. تفقد ما إذا كانت أصفاد القميص مريحة وتحتضن رسغك. تفقد الأزرار. تفقد ما إذا كان القميص مريحًا حول صدرك ووسطك. ارفع ذراعيك. أغلِق أزرار القميص حتى أعلاه.
