Pajamas

Pajamas were a type of clothing usually worn while sleeping.

Starfleet uniforms were often mistaken for these by those who were unfamiliar with them. In 1893, the bellboy at the Hotel Brian mistook Data's uniform for pajamas. Later, while talking to the android, he expressed his wonder at the idea that a man could ride into town in his pajamas and win enough money to build a horseless carriage and make a million dollars. (TNG: "Time's Arrow")

In 2024, Vin expressed his admiration for Captain Sisko's uniform, also erroneously believing they were pajamas. (DS9: "Past Tense, Part I")

In 2152, Denobulan Doctor Phlox wore pajamas while hibernating in his quarters. (ENT: "Two Days and Two Nights")

When Nog sold his possessions in 2372 prior to leaving for Starfleet Academy, Rom purchased his pajamas for two strips of latinum. Later, an enraged Quark ripped the clothing from his hands. (DS9: "Little Green Men")

In 2376, when Tom Paris was accused by Tuvok of altering one of the Vulcan's holoprograms by putting pajamas on the Oracle of K'Tal, he made a joke of it, suggesting, "Well, maybe he overslept." Paris was not responsible, however. (VOY: "Live Fast and Prosper")

In -, Lt. Cmdr. S.E.G.A. wore pajamas when she was linked to the holodeck when Captain Wesley Crusher and Lt. Cmdr Stephanie Thomas observed her dreaming program. Crusher complimented on her pajamas. S.E.G.A. revealed that Cmdr. Lauren Johansson gave them to her on her birthday.
