I'm sorry, but I would also say "no" to the pink. As I was reading your post, all my alarm bells went off.
Mind you, I don't work in OB/GYN, but even in my clinic pink would be an unfortunate choice for interview wear. (work wear would be a different matter.)
French braid or soft bun for the hair. Not loose. (again, *after* the interview loose hair might be ok for work wear)
New shoes. Always make sure you are wearing the best quality best fitting shoes you can find and afford.
And scr*w the little Barbie purse thing. What kind of baby-doll world did that order come from? Was that from the faculty advisor? The female docs I see carry portfolio bags, not dollie purses and Pee-Chee folders.
