One of the most popular shows on television is making Melissa Saunders the star at her prom.

The senior at St. Hubert Roman Catholic High School wrote to the producers of "Desperate Housewives" last fall, after seeing her dream gown on the show. The lacy, rose-colored dress was worn by actress Eva Longoria (search) as she mowed a lawn in the pilot episode.

Saunders wrote that she loved the show and that she wanted photos of the dress so she could shop around for a similar dress at a reasonable price.

"It was our very first piece of fan mail," said wardrobe assistant Roemehl Hawkins (search), the staffer who read the teen the gown to Saunders, who is the same size as the diminutive Longoria. The show's seamstress even added a lining to make it prom-modest.

The one-of-a-kind gown was designed especially for Longoria by Los Angeles designer Eduardo Lucero.

"I'm so excited," Saunders said Thursday, the day before the prom, as she modeled the dress for her gushing classmates. "I cannot wait. I'm a little nervous about wearing the dress and spilling something on it but I'm so excited."

Saunders said she knew the dress was the real thing when she noticed something on the train: pieces of grass.

"Eva Longoria sent me a framed, autographed picture of herself so the grass will go in there," she said. "In my living room."

The dress goes back to Hollywood (search) on Monday.
