understated pearl earings and necklace. Purfect!
Navy suit. Purfect.

And agree with everyone else about the shoes. Black, CLOSED TOES, LOW to medium heel purfect!

Neutral color hose goes without saying. NO BARE LEGS.

shell/blouse: agree with others. bit less revealing.

Definitely one bag/purse.

In addition, carry a copy of your CV just in case one of the interviewer forgets to bring with them for your interview. Also read up about their practice. How long in business, specialty?...

My field is different; nonetheless, it is also very very conservative. Unfortunately, the dress code is sooo lacking.

Wish you lots of luck and try to relax, exude self confidence, be friendly.
