Good Girl Art usually shortened to GGA, is the term that describes certain types of Vintage Art, and specifically Paperback Cover Art.

Richard Lupoff in his The Great American Paperback defines it as "A cover illustration depicting an attractive young woman, usually in skimpy or form-fitting clothing, and designed for (mild erotic interest). The term does not apply to the morality of the 'good girl', who is often a gun moll, tough cookie, or wicked temptress." It is unclear how this term originated as it is usually applied to attractive sexy young women who are either in peril or are perpetrating the peril like my favorite gun moll on the right.
