" But convention matters.
Humans make rules that govern behavior. (Actually, all species do; ours are simply more numerous and elaborate.) Without those rules, we’d have not only anarchy, but shorter, less pleasant, more dangerous lives.
One of the ways we transmit signals about how to behave is through dress. If we walk into a room full of men and women in formal attire, we don’t start doing jumping jacks or get down on the floor for yoga exercises. We don’t think it odd to see bikinis on the beach, but we would be shocked to see them in the boardroom. Conventions differ between cultures and change over time, but no society, even the most liberal, dispenses with all conventions.
We’ve gone from jeans in the workplace to pajamas at the mall. What’s next? It’s hard to imagine we could become more casual in our attire than we already are, but then I never thought I’d see someone in his jammies at the supermarket.
But wearing pajamas in public isn’t just unconventional — it’s juvenile. It signals that the wearer is not a full-fledged adult. Babies and toddlers wear onesies, so why are we now marketing them to adults? And while it might be OK to see a 3-year-old sitting in the grocery cart in her pajamas, do we really want to see her mother similarly attired? We can excuse the child for not changing his clothes before he meets the public, but his parents?
The message the wearer sends is “I’m lazy” — and maybe a tad dirty, too. It’s hard to imagine someone hopping out of bed and into the shower and then back into what he wore to sleep before heading out the door. Or are we to assume that the wearer has drawers and drawers full of freshly laundered PJs for all occasions?"

Totally agree.
