How did Joan of Arc’s male clothing become part of the charges at her trial?

During the trial of Joan of Arc, her choice to wear male clothing was cited as evidence of her blasphemous presumption and her rejection of the authority of the church.1

The charges against her were based on the contention that her behavior, including the wearing of men's attire, demonstrated a defiance of established norms and a preference for her own perceived divine revelations over the commands of the church. While she initially agreed to wear women's clothing as part of an abjuration to avoid execution, she later resumed wearing male attire. She explained that she had made this change of her own free will, stating that her voices had censured her for her previous abjuration. This return to male clothing was interpreted by her judges as a "relapse" into heresy, which ultimately led to the decision to hand her over to secular officials for execution.12
