Am woman; I simply opt out of all that rigmarole (such a good word!) and I'm so glad I work in an industry where it doesn't matter. I don't even wear a bra because I can't be bothered with an extra garment for the sole purpose of concealing my nipples. (Chestier people often appreciate their bras, but I'm not generously endowed enough to need the structural support.) Never been called out on any of it, even the bralessness, in professional contexts or otherwise. (I know some will think that's inappropriate — don't care, you'll live.)
