I think they look daft in public, I never understand why parents let their kids walk around a shop in onsies and pj's.
I wear sweatpants and pjs in public I don't think there's anything wrong with it at least I'm not nude
Why does it matter if they're making a quick trip somewhere for something? I mean if it was like your outfit for the day and you were going all over the place, I agree. But I think generally most people wear them when they aren't trying to impress anyone (lazy days).
In middle school there was this kid that wore pajama pants to school every day. It was kinda weird, but I mean, whatever he wants.
