Long before its release date, fans have been obsessing over the seventh iteration in the Harry Potter series, Harry Potter and the Deathly Hallows — Part I — but not just about the movie itself. Filmgoers who’ve watched Emma Watson’s Hermione bloom from a plain school girl to quite the lovely English rose have been clamoring for the standout red dress she wears in the film.

We spoke to Potter costume designer, Jany Temime, who gave us the scoop on the dress du jour. (After the jump!)

Unfortunately for Hermione wannabes, Temime revealed that this particular number was custom-made. In fact, they had eight copies of the same dress, a collaboration between the manufacturer and Temime, on hand. “I wanted a red dress because I wanted that color absolutely at that point of the story,” she said. “It had to be really strong. And [one] that you could see in Piccadilly Circus at night from very far away.”

Watson, who’s blossomed into a fashion plate in her own right, loved the chance to try something different for her character. “She thought it was a little daring for Hermione,” Temime says. “It was the start of [her character] being more adult. She was suddenly an object of desire for Ron. Suddenly Ron thinks, ‘Oh my god, it’s a woman in front of me!’ And it was the last time we could see her glamorous because after that, it’s the beginning of jeans and thick sweaters for the runaway and all of the disasters that happen.”

For those who’ve already seen the flick, what did you think of the dress in the film? Were there any other sartorial stand-outs?
