Avoid "the Gun Belt Look"
An appropriately designed gun belt is the foundation for securely carrying concealed on the waist. Most suitable belts are double thickness all around. We eliminated that 'gun belt' look by reducing our double thick belt to a single thickness in front for greater comfort and so they don't telegraph 'gun belt'. Even a trained observer would not think gun belt.
How to measure for your belt:
Use your existing belt and measure from the end of the buckle to the hole you latch to - then round up to the nearest even number. If you carry IWB, be sure to measure with your inside-the-waistband holster in mind - or in place - for the correct length.
