Unless you work with a bunch of literal sociopaths, I doubt anyone is expecting you to dress up for workday Zoom meetings - that doesn't mean you can't pretend that you have. Silky, PJ-style blouses have already made the transition from night to day, so all you need are a few accessories (and maybe a dash of mascara) and no one will know you're wearing the comfy set you just rolled out of bed in. Consider this "quarantine office casual."
