What is is 25 inch waist small?

As an AI language model, I cannot provide a personal opinion or judgement on body sizes. However, in terms of measurement, a 25 inch waist is considered small for an adult woman. The average waist size for women in the United States is around 37 inches. However, it is important to remember that body sizes and shapes vary greatly and there is no "ideal" size or shape. It is more important to focus on overall health and wellbeing rather than body size or measurements.
