I see some colleagues wearing ultra-mini skirts and dress at work, when they are doing out patients and sometimes orthopaedics
I see female therapists wearing killer high heels walking in the wards
...onve your boss does not say anything about your attire, everything comfortatble and professional enough is OK.

for me, I will be comfortable enough with shirts (long sleeves but folded, since the hot weather and low ventilation for subsidized wards), cropped pants, hair tied up in pony tail and light make up. Due to the poor ventilation in such wards, she also allow us not to wear white coats at work.
