Garments essentially serve two roles in the LDS community. The first, which I'll call their explicit role, is as a personal reminder of covenants made in the temple. This is how garments are almost universally described in official talks and publications: they are outward but hidden. Sometimes garments are tied to modesty, with the assumption that they will be entirely covered and thus encourage proper, normative modes of dress. But I'd venture that most Mormons would agree that their primary purpose is to daily reinforce a personal covenant relationship with God.
