Well, It does make me feel a bit weird... After all, I'm not going for the "sexy prof fetish" here, but for scholar and authority in a college level class room--I have no interest in setting a sense of sex appeal on the job market or in the classroom. Given the horrible job market for academia right now, standing out matters and being able to convey that I'm an authority on my topic and in my fields matters even more. This is especially true not only in job talks, but in the classroom as well. I'm in front of young men and women, who think they are on top of the world and they know EVERYTHING, so why should they listen to some five-foot-tall woman, cause she's just a woman, WTF does she know anyway. I also look younger than my years.... Does that make sense? But no, that doesn't make you a bad person. Not in the least.
I think you're right about the RAW idea. All one needs is a convincing costume and the ability to act like you know what you are doing.
