looking for advice.

looking for advice. I have a supervisor of our office for attorneys. I am also an attorney. for the last couple months she tells me that I am dressed unprofessionally even though I am in a dress and cardigan and nice expensive tennis shoes.. when I do not meet with clients or see clients and stay in my office I like to wear shoes with support as I have bad knees and keep my heels in my office just in case. One time when I was asking her work questions she interrupted me to tell me that I need to shower and wash my hair more and it looks like I had not showered in a month. I informed her that I did shower the night before as well as wash my hair. she at a later date brought me products, not knowing my skin history as well as tried to get me to have an appointment with her hair lady. There have been numerous comments about my hair or my attire and shoes. I am one of two female attorneys the other female is the one saying the comments. I have seen the men wear tennis shoes, cowboy boots, khakis, and look disheveled when meeting with clients yet nothing is said to them. our employee handbook does not have a dress code it only says no radical departures from conventional dress. however I am also afraid to say something to other supervisors as she holds a high position and she is considered irreplaceable. however the constant harassment and tear down has been very harmful. anyone have any tips?
