Belt up!
DON’T worry about a belt creating a round tummy underneath. I hear this from my clients all the time. It may do, but only you will notice it. All other eyes will be on your wonderful hourglass figure.
But do avoid belting if you have a thick waist. Trying to create the illusion of a defined waist with a belt doesn’t work and, worse, it only draws attention to the fact your waist is not so well defined.
