What is a one-sentence summary of the following article?
Because tuxedo pants fit higher up around your waist than jeans or dress pants, which sit around your hips, you need to take different measurements instead of providing your pant size as you normally might. Using a tape measure, measure around the top of your hip bones and across your navel to determine an accurate waist size for a tuxedo. To make sure that the pants fit comfortably, take care to do this step properly. This can be done over your pants. Place the tape measure around your hips, where the hip bone juts out at its biggest point. Then, continue wrapping down around the biggest part of your backside. This will help to make sure that your trousers are roomy and comfortable. The outseam refers to the seam the runs along the outside edge of your leg. This measurement needs to be taken while you're wearing shoes. Measure from the outside arch of your shoe, pulling the tape measure up your leg, past your hip bone and to the height of your navel. This measurement helps determine the length of pants you will need. Make sure the shoes are similar to what you'll be wearing with the tuxedo, in terms of height. You wouldn't want to do this barefoot, or wearing big-soled cowboy boots. The is usually most easily measured on a pair of pants that you already own, rather than while you've got them on. Fold a pair of pants that fits you well flat on its side, so the seams are even. Fold one leg up and out of the way, then measure a straight line from the crotch seam to the bottom cuff of the pants. Depending on the tailor or the rental place, some shops will ask you for both in and out-seam measurements, while others will only ask for one or the other. Make sure you find out what they're looking for, so you don't provide the wrong measurements.

Summary:
Measure your waist. Take your hip measurement. Measure your outseam. Take your inseam measurement.
