The Alamy website is a treasure trove of, erm, fashion...

All those photos confirm to me that she thinks gender is all about clothes. It's all a dressing up game. Once again she diminishes the serious subject of gender non conformity and is dangerous to the cause that she is meant to champion.
Back (again) to the passing out parade. If she loved her job, was so interested in it she wanted to progress, and was so knowledgeable, she would have worn the skirt. We all make sacrifices for work, it's not like she never wore skirts, so not much of a sacrifice really. It clearly was a rebellious outburst that she thought she could get away with.
I agree that if true, forcing women to wear skirts in 2010, or whenever it was, was ridiculous. But you don't change attitudes and procedures by throwing a timmy tantrum. You change them by engaging with the Union to ensure that no one else has to make the same choices in the future. It's for things like this that the equalities legislation (though it's not without flaws) was created.
In her own words to her son "mummy is a girl sometimes and a boy sometimes" (though to me that is gender fluid not non binary, but
) Why could she not be the "girl sometimes" whilst going through the ceremony, and a "boy sometimes" when she returned to her daily work? Then she would have been able to take up the cause.
