In high schools, colleges and the like, it is often impossible to carry on very much of a conversation during, or even between classes. Since many dates between boys and girls are most easily made when they are gathered together in school, it is a disadvantage not to be able to tell whether a girl is already dated for a particular day and hour. If a boy knew that one girl is already dated for the particular time he desires, he would quickly be able to attempt to date another girl who was not already dated. However, up to the present time, this has been difficult because, in many instances, there is not sufficient time to talk to every available girl to determine their date status. In order to remedy the above situation, it is one object of the present invention to provide an article of wearing apparel which can be set to indicate to any observer whether a girl has a date for the particular time desired.

A mirror has an upper portion which is held in flat condition by being secured in the upper portion of a vertically extending frame. The integral lower portion of the mirror is flexible, and its curvature is variable about a vertical axis, so that by varying the curvature of the lower portion, there is provided an image of the appearance of a person's body after a weight loss, the upper flat portion reflection a true reflection of the person's face, which would change comparatively little, if at all, after a weight loss. The curvature of the mirror lower portion is varied by rotation of a knob threadedly engaging a screw that moves a lever connected to the mirror. The mirror is supported on a stand or a wall support by a vertically movable member in a hollow tube at the back of the mirror, so that it may be vertically adjusted to reflect the face of people of different heights in the flat portion of the mirror.
