Alternative costume ideas for Goddess Athena in my play?

Part of me thinks nothing could be tackier than putting her in army surplus un-type-cast costume…

or any other ideas?
or is that better than the other ultimate tack at the really long white and gold Grecian gown

In the play she uses her shield to save the day (paraphrasing) reluctantly, saying she is going into Athens this evening

God of wisdom and god of war…
