If you’re sagging your jeans without a belt, keep to only an inch or two extra in the waist. Any more and you’ll have difficulty keeping them on.
Some types of jeans like joggers make use of elastic waistbands that gather and bunch around the waist to prevent them from sagging. The scrunchy elastic will ensure that the pants hug the hips while sagging, which will keep them up, but may have a tendency to rest a little higher up. You may spend more time adjusting pants with elastic waistbands.
For most people, a few inches below the hip bones, right around the crease of the hips, will work best, because the jeans can sit low while being held up by the contours of the butt and thighs. Remember, you’re trying to look good. Sagging any lower than about the upper thigh will expose your crotch and make you look ridiculous.
Try not to sag so low that the waistband of your jeans constricts your movement while walking. Resist the urge to pull your jeans up or down constantly, as this looks less like a cool, effortless slouch and more like you don’t know how to wear clothes that fit you.
Bright colors and patterns like plaid look good under sagging jeans because they provide a little visual contrast. Be careful: the dress codes enforced by certain business don’t allow pants to sag excessively, and some states even have laws in place that can hit you with a fine or jail time for wearing pants so low that they expose undergarments.

Start thinking of your underwear as part of your outfit, rather than beneath it. Buy designs you like that complement the types of clothing you tend to wear. You can also sag to show off the waistband of your underwear if you tend to wear prestigious designer labels. This is an especially popular look with younger male celebrities.
Athletic pants like sweats typically feature elasticized waistbands that will be both an advantage and disadvantage when trying to keep them in the right place.
