Well, their intention doesn’t matter, only my emotional response does. Even if my coworkers meant nothing by it, or want to make me feel good, or whatever, my actual emotional reactions are what will control my behavior.
I guess that’s significant, because I don’t think many people are consciously aware of the role they’re playing in the perpetuation of social norms. I’m sure most of my coworkers would have, in theory, wanted me to wear “what I wanted” while at the same time leading to my feeling uncomfortable when I did.
Anyway, +1 for dressing like a slut. Go you.
