Now, fit is everything when it comes to a short-sleeve button-down. You’re most likely going to wear the shirt untucked. So, make sure the tail and hem hit just below your beltline. You want it to feel fitted but not tight. When you try on a shirt, test out the fit by sitting down. When you take a seat, does the shirt cling to you too much, or is it as comfortable as it was when you were standing? Can you move your arms without the buttons feeling constrained? Lastly, pay attention to the sleeves. They should hit just about mid-bicep and be neither too loose nor too tight.
