Does anyone wear pyjamas?

Do people still wear pyjamas?

Does anyone younger than 60 wear pyjamas? Curious to hear an argument for them from someone who is a strong believer in the pyjama, but I don't know what it could be... #asknostr

Why not just wear a t-shirt and/or boxers? (I'm not counting people who sleep nude here).

Is it an idea of wearing this almost formal bed attire / bedtime suit to greet sleep, a routine? Maybe there's something to that, I just don't think I'd find them comfortable.
