UNICORNS.

But here’s what memory alpha has to say about those. 

In Evolution: This episode marks the first appearance of the high collared style of uniforms, which are used by the cast throughout the rest of the series’ run. They cost $3,000 each to make and were made of breathable wool gabardine to give greater comfort for the main cast, many of whom had begun to suffer back pain as a result of wearing the older design. Only characters above ensign rank initially wore them, with background performers retaining the old style “jump suit” and these uniforms were later used in some episodes of Star Trek: Deep Space Nine and Star Trek Generations. (Star Trek: The Next Generation Companion, p. 99)

In Booby Trap: This episode marked the first appearance of the final version of the Starfleet uniforms used in the series. The seams running down the sides of the chest were removed, the shoulder pads were made smaller, and an elastic waistband was added to the bottom of the uniform top. Only Captain Picard is wearing the updated uniform in this episode.

5 episodes in and it’s “we need to change the $3000 costumes we just bought!!”
