Widths vary, but opt for a belt that is at least as wide as your palm. It should sit at the narrow part of your waist, not on your hips. [2] X Research source Narrow belts tend to slip down the hips, forcing you to pull at them all day.

Just like bras, there’s no one-size-fits-all garter belt, and being able to adjust the straps is key to a good fit.

For most garter belts, all you really need is the waist measurement. However, if you plan to wear the belt at hip-level, you’ll need the hip measurement. Either way, it’s not a bad idea to have both. Write down the measurements in inches and centimeters (this will save you from having to convert later, since brands may use one or the other).
