On Star Trek: Discovery, at any moment you may be in command. We'd advise that you sleep in your uniform but that's uncomfortable and also you'd just have to iron it when you get up, so instead head to your quarters wrapped in this Star Trek Discovery Adult Fleece Robe. One size fits most Starfleet officers, but Saru's limbs are going to look a bit awkward in this bathrobe until he gets it tailored.
