When the invitation or save the date for a future wedding makes its way into your mailbox, you may find yourself bursting with excitement. Even the perpetual wedding guest can admit that weddings tend to be a lot of fun. They are a chance to eat good food, flirt with an open bar, and dance beside old friends and brand new ones. It's also the celebration of two people in your life who have found love within one another and promise to stay together for a lifetime.

Weddings are a chance for you to let loose and have a great time. But when doing so, it's important to remember that weddings are also a gathering of all different people, of all different ages, so you should try to keep your behavior as classy as possible.

You should also remember that as a wedding guest you're a representation of the bride and the groom. You're not just there to bust out dance moves and stuff your face with expensive-tasting food, you're there to support and celebrate with the happy couple who just pronounced their “I dos” to each other.

In order to avoid showing up at the wedding already hung-over, or finding yourself tending to blistered feet halfway through the reception, avoid these 34 common mistakes and ensure that your wedding guest reputation stays untarnished.
