Bridal Wedding Etiquette

This was a random fact that came up on Mad Men last week. I think Pete was the one that said that you say congratulations to the groom and best wishes to the bride. I looked it up and apparently you can also say best wishes to the groom. I have no idea what would happen if you said congratulations to the bride. Really when you think about the meaning behind it, it's quite outdated and a little bit sad. Nonetheless it still seems to be etiquette even today. As for me, I usually just say congratulations to both, I'm a rebel.
