You'll be able to find the proper size for your underwear across brands if you know your waist and hip measurements. Use a tape measure to measure your natural waist and the fullest part of your hips so you can choose the most comfortable size for your body. You can find your natural waist by bending sideways. A crease will form at your waist to help you identify it. Keep the tape measure parallel to the ground when you measure your hips. It's a good idea to measure both your waist and hips twice to make sure that you get the same measurement both times. Once you have your waist and hip measurements, you can consult the sizing information for any underwear you're considering to ensure a proper fit. Checking your measurement is important, because sometimes you don't get it right the first time. If your measurements are different on the second try, measure them a third time. One of these sets should match up, so use that set of measurements when shopping. No one wants to be pulling at their underwear all day to keep it from slipping or falling down. Choose underwear that has firm elastic in the waistband so you know it will stay in place. While firm elastic at the waist is helpful in underwear, avoid styles with elasticized leg holes. They have a tendency to bunch up, which can be uncomfortable. Underwear that's too tight doesn't just lead to unflattering bulges and lumps beneath your clothing; it can also cause skin chafing and irritation from the friction. In general, any underwear that's tight enough to leave marks on your skin is too tight. Underwear that's too tight also doesn't breathe as well, so it can lead to health issues and leave you a little sweaty. Before leaving the house for the day, it's important to make sure that your undies are lying smoothly against your body. Any pair that bunches, rolls, or sags under your clothing is going to be uncomfortable because you'll be tugging at them to keep them from pinching your skin or falling down. Not only can bunching underwear be uncomfortable in the long run, but it can also look messy and ruin even the best outfit. This is especially important with dresses and skirts! If your underwear is bunching, readjust it so that it sits properly on you. If it still bunches, switch to a different pair. Bunching, rolling, and sagging is often a sign of old, worn underwear; it means that the fabric has lost its stretch and is now too big for you.
Measure your waist and hips. Double check your measurements to consult sizing information. Look for firm elastic. Avoid underwear that's too tight. Check for bunching, rolling, or sagging.
