Styling a navy blazer

Did you do any black Friday shopping?  Me...not so much.  I did however snag this new navy blazer from J.Crew.  I had a go-to navy blazer from Ann Taylor but over the last year I noticed it hasn't fit as well.
I wasn't really on the hunt for a new blazer but once I tried this one, I bought it on the spot.  Now, how to wear this perfectly fitting blazer outside the office.  I found several casual styles that I think I can make work.  What are your favorite ways to style a blazer outside the office?
