version of the uniform with bare legs and boots ("skant"). Beverly Crusher often wears a blue laboratory coat over her standard uniform, beginning in TNG: "The Naked Now." The lab coat was used extensively to hide Gates McFadden's pregnancy in the fourth season. The blue tended to appear teal under certain lighting conditions in the later seasons and subsequent spinoffs. In some episodes of the later seasons, starting in TNG: "Darmok", Jean-Luc Picard would sometimes wear a different uniform that consisted of a gray shirt with black ribbed shoulders and collar with a "bomber jacket" that was red overall with black ribbed shoulders, often worn open or very loosely fastened. The uniforms could be fitted with pouches for carrying tricorders and Type 2 phasers on the waist, and the early versions had a small pocket built in on the left side of the waist for carrying a smaller Type 1 phaser when appearing openly armed was not desired. The removable gear pouches were also incorporated into the uniforms used in DS9 and the TNG-era films from First Contact onward. In the show's early seasons the uniforms were one-piece jumpsuits made of Spandex, and sized slightly too small so that they would be stretched when worn and provide a smooth appearance. But the cast members hated the uniform's painfully tight fit and lack of pockets, and after Patrick Stewart's chiropractor warned that they risked permanent injury, the actors persuaded the costumers to gradually replace them with wool uniforms. The wool uniforms, which most main cast members wear from the third season onward, are two-piece (tunic and pants) designs that lack colored piping on the shoulders and edges of the pant leg cuffs and have a raised collar. The collar of the tunic has a colored piping similar to that of the original diamond-shaped shoulder piping. The spandex uniforms continued to make appearances throughout TNG, usually worn by extras in various scenes. These were later altered to lack the piping on the shoulders and trouser hems and include a raised collar as a cost-cutting measure. Admirals wore numerous different uniform variations in the early years of TNG; a final design was settled on for all admirals in the sixth season onwards, featuring a jacket with gold piping along a centered front closure, and rank pips (indicating the number of "stars"), in gold squares on either side of the collar.
