Nr. 1 is very eyecatching, but red dress is also gorgeous! I said WOW to myself for both, but I was actually going to say nr 3 -when read that is a meeting rather than a regular interview, so that's changing everything!
Go with nr. 1!!!
or
the fab dress from nr 7 + the same jacket from nr 1.
(and dressing like that, I would say the same as Deborah said:-))by the way, is it a man who are you meeting with?-then no problem! or is a woman wearring a grey suit all the time(no pun intended)...you have to be carefull with those:-)))
Good luck!
