Uh: ''suggested that women have little value aside fromt heir ability..."
Sorry about the dropped word.
So a depiction must always show ALL aspects? Why?
No. As mentioned before, what a person wears in his or her own private life is just that: private.
But one must be aware of the image that one is conveying when one is working in a professional setting. For example, if I were to wear a t-shirt that read:
"A woman needs a man like a fish needs a bicycle" while at work, men working with me might feel that I did not value men. If I were to hang up a sexy fireman's calendar in my cubicle, assuming they are all covered up but wearing tight clothing that shows off very buff bodies, airbrushed where needed, overly sexualized, then the men I work with might worry if I took men seriously or if I only saw them as sex objects. If I wore a t shirt similar to the one the man was wearing, only showing similar images of men, I would not expect to be taken seriously as a scientist. In fact, if I did any of the things mentioned previously, I would expect to be reprimanded, told never to wear that t shirt to work, to get rid of the calendar and perhaps worse. I cannot imagine being allowed on camera wearing a similar garment. Yes, my employer is fairly conservative in terms of image. If I were working in a tattoo parlor or Spenser Gifts or something like that, it would be different. In such work places, employees frequently wear provocative clothing and in fact, that is often encouraged.
In the case of STEM fields, the fact is that the culture exists that often is discouraging, at best, to women and sometimes demeaning. Plenty of women report a lot of overtly sexist behavior. If you want to convey the message that all persons are welcome and respected, regardless of race, gender, sexual orientation, ethnicity, religious background, then you don't wear clothing that might convey the opposite.
