Do you know how much the Rebbe spoke about women waering shietuls?
Sure, because he knew, first hand, that wearing a different kind of covering often leaves the hair partially uncovered. In the famous picture of her, which is on the official Chabad website, she’s not wearing a sheitel. Defending her by saying, “Do you know how much the Rebbe spoke about women waering shietuls?” is really odd when she clearly didn’t (always) wear one.
And btw, I don’t only know this from the internet, but that’s the only evidence I can show you.
