Would she probably understand and get use to the idea pretty quickly ?
My SO wears manly PJS because she says they are way more comfortable.
So I doubt any woman could argue that a pretty Olga or Shadowline Nightie is not super comfy to wear and that since she wears manly pjs I should be able ro wear somewhat feminine pjs.

Has anyone tried this argument, if so what was the reaction ?

Also how long do you think it would take before she even stopped noticing you floating around in the Nightie ?
