Completely absurd, gaw. A woman outside the four walls of her home, with the shades drawn, is absolutely required al pi halacha to be fully covered per all the requirements in hilchos tznius.
And if her shades are open into her home, she must be dressed tznius even within her home when people in the public can see her inside. Same is true if she has guests in her home who are not immediate family members. (Even if they are spouses of immediate family members.)
