While I don't think there should be an objection to feminine dress, there is a difference among young students today. My sister is an RN, on the job less than 10 years (still looks 16 herself!), and she recently complained about how the new medical students wear their scrubs. Apparently, there is a trend in rolling down scrub pants to show hip-bones, and to imitate low-rise jeans.
My sister has always loved not having to think about work clothes, and loves having her job provide her with comfortable clothes that allow her to do her job without having to worry about putting on a runway show, or being judged on how feminine or professional she might look. The new students coming in are turning this uniform into a more skin-showing "personalized" statement.
I don't know if I could take a young doctor seriously if I was staring at her navel.
