The idea that wearing red means you slept with the groom is as ridiculous as the idea that brides wear white because they are virgins. Both are ridiculous concepts and any "tradition" that espouses either idea needs to be completely ignored, IMHO. Red is a perfectly lovely color (my personal favorite color, actually) and white wedding gowns, while lovely, have never meant the bride is virginal. It's only ever been a fashion choice. I don't know who comes up with these ridiculous rules.
