Anytime you shorten a pair of pants, shorts, sleeves you are also changing the intended diameter of the garmet. For instance, if you hem a pair of shorts from 11.5" to 7.5" the leg opening is going to be too big...versus if you took a 9" short inseam and hemmed to 7.5" which wouldn't be as big but still should be tapered. Your tailor can shorten and taper them for you... and my tailor only charges me for the hem. This is especially true for pants. Another example, I'm 5'-7" and have a 38" waist and 27" inseam (picture an Oompa Loompa without the face paint and gloves). Buying a 38W x 34L will require more tapering vs. a 38W x 30L. Short story long, cheaper to find clothing you like that is too long at a great value and have them altered... and I need to eat less donuts.
