What metaphors are used in Marry the One Who Gets There First by Heidi Julavits?

The bride and groom are sometimes shown semi-dressed, their physical nakedness a kind of visual metaphor of the stripping away of the masks through which they hide their real selves that occurs in the text. Louis, for example, is shown just out of the shower with only a towel around him and cutting himself shaving; Violet appears in nothing but her panties and also half-dressed with her hair in rollers. She is also shown in other unguarded and unflattering snaps: receiving a pedicure; in her bathrobe, hair wet, making a phone call; adjusting her garter just before she enters the chapel. It is as if the photos take the reader backstage at a theater. The
characters are about to go onstage and play certain roles, but the reality of who they are outside the show is very different. The photos reveal life more as it really is, behind the staged glamour of the big wedding.
