This term refers to the practice of advertising one's religiousity by wearing significant decolletage and having a cross suspended between the breasts. This is especially effective if the practitioner has either very prominent breasts or is not wearing a bra.
Jessica, who was both very religious and had been embarassed by her rather prominent breasts, made them into a spiritual asset by practicing decolletage ministry. She found it more effective than the John 3:16 signs.

This is a layer of fabric added to thin halters or bikini tops in order to make its underlying features less evident.
I once bought a bikini top that had really thin fabric; Mom insisted that I sew in a modesty layer underneath or even wear a bra.
