Sweetheart, there is no way you could know it, but this subject has been beat to death on lots of other threads. Look in the upper left of your screen and you will see a little "search". Click on that and the world is yours!
There are answers to your questions from pantyhose color to tie pattern as they relate to interview success. Good luck.
