Sizing
The right fit, from mile one.
Have a friend measure while you stand straight. Tilt your head forward to find C7 (the bony bump at the base of your neck). Put your hands on your hips with thumbs pointing back, slide up to the top of the hip bones, and measure along your spine from C7 to the line between your thumbs. For the belt, measure around your hips at that same height, which sits a little above your pant waist.
