Costume designer Robert Blackman was concerned about the re-creation of the Klingon uniforms seen in "The Original Series" as he thought that the metallic material used would be nearly impossible to create accurately. He was subsequently relieved to have found four original costumes and an additional shirt in the costume archives, calling them a "godsend". His team created patterns from other costumes to remake them. Makeup supervisor Michael Westmore had previously worked on a television series during the 1960s and recalled what type of makeup was available at the time. He had the team restrict themselves to techniques of that era to ensure that the "DS9" crew blended properly into the scenes. The hairstyles of the crew were meant to be reminiscent of "The Original Series", with Alexander Siddig sporting a style previously seen on James Doohan. René Auberjonois said that Siddig's new hairstyle reminded him of Jerry Lee Lewis.
