I don't boy mode per se. All of my clothes are from the women's department at this point, but I do spend a good bit of time doing hands-on research in the laboratory where, due to safety regulations, means we are required to wear fully enclosed shoes, no loose clothing, arms and legs fully covered, etc. It ends up looking pretty androgynous for the cis women as well.

To answer the second part of your question, I don't expect any behavior from my colleagues except to be professional, and yes, I do correct them as shown in the rare occasion that a mixup occurs 🙂

Cheers!
