1 Bust a Move? No Way!
Because wardrobe malfunctions are a no-no, well-endowed contestants like Kirstie Alley have supportive bras sewn into their dresses. That way, their upper regions are secure and they "focus on the 'rhythm sections' below to move," says DWTS
costumer Randall Christensen.
2 Bring the Bling
It's not uncommon an hour before the show to see the wardrobe department hard at work meticulously hand-gluing individual Swarovski crystal rhinestones to the dancers' costumes (like Ralph Macchio's jacket). "We go through 1.25 to 1.5 million rhinestones every season," says Christensen of the jewelry.
3 Look, Ma, No Pants!
After the show, judges Carrie Ann Inaba, Len Goodman and Bruno Tonioli have a ritual: "We sit outside our trailers and have a glass of wine," says Tonioli, who imbibes while wearing just a robe so he won't wrinkle his suit pants. Laughs Inaba: "He's always walking around with much less clothing than he should."
4 Tan-y Dancer
pro Cheryl Burke is very attracted to the ballroom's dark side. "I'm addicted to spray tans!" she says. "I have a stash in my trailer. The more they say tone it down, the more I will put on."
5 Short Cuts
Kendra Wilkinson asks for her skirts to be as tiny as possible. "That's my motivation," she says. "I want to look perfect in them, so I have to eat and work out perfectly."
6 By the Book
Remembering his choreography is a snap for Pittsburgh Steelers wide receiver Hines Ward, who keeps an NFL-style ballroom playbook. "I write the moves down in football terms so I'm more comfortable," he says.
