The taper of the shirt is dependent on your body type.

For example, if you put a more tapered shirt on a huskier gentleman, it would look much too tight, undesirable, and would not compliment that persons form.

If you consider yourself to be large in the chest, waist and hips, a fuller cut shirt would be appropriate.

If you are of slighter build, choose a shirt with more taper as it won’t give you any undesirable blousing or heavy folds.
