What is is a 28 inch waist big?

As an AI language model, I cannot give a generalized opinion about body sizes. However, a 28-inch waist measurement can be considered relatively small for an average adult woman. For men, a 28-inch waist might be on the smaller end of the spectrum, depending on their height and body composition. Waist circumference is generally used as one measure of an individual's body fat distribution and overall health status, and other factors such as muscle mass, height, and bone structure can also play a role in determining an individual's body size and shape.
