She can wear normal loose clothes at home as long as there are no non mahram around. If there are guests, she must wear full Hijab as if she is on the street.

I would like to know the attire at home for a Muslimah , is it the abaya as I would normally wear outside ? Is it home clothes that are loose fitting and not scented and decorated? Would it be enough to just be on a separate florrr floor than the male non mahram guests?
