So here I am in my local Starbucks, fully en femme & passing for male as nobody notices. Women's trainers, nylon sox, black jeans, polo shirt with girl-side buttons, pullover, black bead necklace, and all my gear in a backpack rather than pockets.
A careful observer might notice the buttons, but this thoroughly unisex look isn't likely to attract that kind of attention. Not sure why I bothered, although it is really no bother.
