6 Things to Know About Scully's Style Evolution on The X-Files

"Both Gillian and women’s styling have changed since the original series," Hargadon tells InStyle. "The suitings of the '90s were looser with padded shoulders, and much of that decade was still a carry-through of the '80s. Gillian is a sophisticated, beautiful woman and I hoped to reflect this in her current style and tailoring."

"This is due in part to her religious background and partly in keeping with the restrained look of a scientist and FBI agent," he says. "Her color scheme is largely within the realm of blues and grays, with rich greens or burgundies being the most vibrant choices."

"Scully’s look is tailored, subtle, sophisticated and confident," Hargadon says. "The fabrics of her suits are beautiful, and the fit is adjusted and proportioned to lend Scully a distinct form of power dressing. I believe this was also the intent in the original show."

"A suit that really stood out for me in the original series was a fitted navy number with a tie at the waist," he explains. "It suited Gillian perfectly and added some panache to her otherwise conformed FBI look. A cropped black trench with a pleated peplum at the back was my homage to this navy suit."

"There are certain rules within the FBI dress code," Hargadon says. "She isn’t undercover, hence appears at work in a suit. I varied the look by combining jackets with dresses or skirts, not always trousers."

"Mulder’s suits were also built for him, so I was able to choose color combinations for scenes with him and Scully," he says. "Normally, unless for a specific psychological message, I’d keep the two in different colors. For example, Scully in gray and Mulder in blue, or vice versa. Since the general lighting overtone of the series is blue, I avoided a complete blue schematic as a general rule."
