Summarize the following:
Tailors, seamstresses, clothiers, and other garment makers generally use tape measures to get the correct measurements of a person when fitting for clothes or altering items. These portable, flexible tools are your best friend when it comes to measuring your pants.  When measuring with a tape measure, pull the tape taut, but don't stretch it. Clothing tape measures are often made of a soft synthetic material that can distort if stretched, resulting in inaccurate measurements. You can also use a plastic measuring tape that you might find in your toolkit. This type of tape measure isn’t as easy to use, but it will still bend, allowing you to measure curves. If you’re measuring your pants to figure out which style and size is right for you, it’s best to use a pair of pants that fit you properly. Ideally these pants will not be too worn out or stretched. The legs of the pants should also extend roughly to your ankle bone, or a little lower depending on preference. Not all types of pants will have the same measurements. Grab a few different kinds of pants that fit you well. Dress pants will be slightly different than chinos, or jeans. The easiest way to measure pants is to lay the pants on a flat surface. If you try to measure a pair of pants that you are wearing, you may not get the right measurements as you shift your body to see the measurements.  Your pants shouldn’t be too worn in so that you can get a realistic measurement. If the pants you are measuring are wrinkled, quickly smooth the fabric out with an iron. Measuring your pants is mostly the same for both men and women. However, sizing for men is typically represented by the length of the measurement in inches, whereas women’s sizes are typically represented by another number.

Summary:
Use a measuring tape. Use a pair of pants that fit you well. Lay your pants flat on the floor.
