Think of a word that means something to wear. Add the letter O in the exact middle, and you will get a phrase meaning "not aware."

HINTS:
1. The word that means something to wear is usually associated with a woman.
2. The word means a set of clothes/accessories.

Answer:

The word is OUTFIT. Adding an O in the middle gives OUT OF IT - which means "not aware."
