Re: about wearing
There are many jobs you can do from home, wearing whatever you want. You can be a freelance writer, a medical transciptionist, a loan underwriter, a database analyst, etc. etc etc. All that you require is a good computer work station.
The person is doing his or her regular job, even though he or she is not dressed the way we dress at the office.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
