Unless you really want to risk exposing your "girls" in front of a crowd, be sure to secure them before you hit the town. In today's day and age of cell phone cameras and YouTube videos, the last thing you want is for your mother to log on and see you shaking what she gave you, accidental or otherwise.
It's a virtual certainty that every "DWTS" contestant with breasts is practically stapled into her costume to avoid a wardrobe malfunction of Janet Jackson-sized proportions. Follow their lead and invest in the appropriate bra or other undergarment to go with your ensemble, and enlist a friend to keep an eye on your outfit's functionality.
And we shouldn't have to say this, but don't forget to wear panties. You don't want to be known as the girl who "pulled a Britney Spears," and we're not referring to her chart-topping or head-shaving ways.
