Modesty is the quality of a personâs being that is demonstrated or shown by his/her moderate and unassuming style of dress and behavior. Modesty is most commonly associated with how a person dresses, particularly that of women or girls, but it is a broader virtue of oneâs personality. It is similar to humility as it is expressed in oneâs behavior. In respect to how a person dresses, it indicates, for the most part, that such a person does not display her or his body in a way that excessively emphasizes her or his sexual attributes.
