To avoid victim blaming, and tis focusing on women's sometimes sexualised clothing, could you phrase it that dressing in a way that is unusual for the setting - presumably dressing differently from her colleagues - she runs the risk of drawing attention to herself as a person, rather than as a clinician. IFSWIM
In clinical work (or most professional work, really), the focus should be on the patient, and nothing should distract either the patient, the clinician, or her colleagues, from that.
I see this is a basic fundamental feature of being a "professional:" I'm an educationalist - my job is to facilitate my students' learning. My personal views, presence, dress, likes, dislikes etc etc distract my students from focusing on their learning. So I dress and act more neutrally than I am when I'm "myself" off-duty. It doesn't mean I'm unfriendly, or dress dowdily, but my professional persona is not my personal persona. IYSWIM
