NC's first qus to SP were really helpful in that regard comparing BU's appearance in court - long hair, make up, dress, with BU's appearance at work in A& E: tall, wearing scrubs, receeding hairline, hair pulled back in ponytail.
Wearing scrubs is almost always going to be a giveaway for someone who has transitioned in name only and in adulthood. People who are conscious of their bodies or have modesty issues have to think ahead about sizing/underlayers.
When I was being really well cared for by a nursing team, when I was half-awake by the bedside of a v sick relative overnight, I knew when a male nurse or doctor entered the room because they made the biggest effort to "announce" themselves and not startle me, and they made sure to give me a lot of space because they were obviously sensitive to the fact that a male nurse walking in on a sleeping woman was different to a female nurse. And as I wasn't the patient, they could have technically been brisk about getting on with the job, but they were being sensitive to the situation, and just behaving like people do when they know they are the ones with responsibility.
BU blundering along with a massive sense of entitlement was always going to be a risk for Fife. The entitlement weighing even heavier than the trans status imo.
