That wasn't a bra. That was a Binder, a specially designed undergarment used to compress the breast tissue into a more masculine shape. Typically, they are used by men suffering from medical conditions that cause breast growth or Transmen that haven't had surgery. (Also, for hardcore Cosplayers that are going as a male character.) They're more expensive than a typical bra and require special ordering.

The flashback in chapter 5 is key, here. The facts we have are that Mutsuki basically checked off the three traits used to define someone that is Transgender. (Like, quite literally, those are the three key traits used in official defintions of the term.) Seriously, the only character that addresses or treats Mutsukis as a woman is Torso -- in other words, someone without any context or knowledge of the individual. Dr. Shiba and Sasaki both intentionally use masculine-gendered language to discuss Mutsuki, and in all ways but surgical procedures Mutsuki is living as a man.

Ergo, until we are given information that explicitly contradicts Mutsuki's own statements of intent and actions, it is appropriate to deal with the character as a Transman because that is what we have been told/shown.
