These photo sessions are typically staged days, months or even years after the initial wedding, and involve a bride wearing her dress in unusual places or while doing offbeat things that result in a "trashed," or ruined, dress.
You can get a funky yarn in an offbeat color and, depending upon how fast you knit or crochet, within a week you might be wearing a top that's similar and yet oh-so-different from what everyone else is sporting!
One recent entry discussed how Moon Unit Zappa, daughter of the late rocker Frank Zappa, decided to name her daughter Mathilda Plum-even though her own offbeat name was relentlessly mocked in the 1970s.
