Thank you for posting a thread like this. I appreciate the courage it takes to ask for comments on an outfit.
Like the others, #3 is my favorite. I think it looks good on you.
In terms of the other versions, it may be a case of too many statement pieces in one outfit. First is your hair. Great hair! No matter what outfit you wear, your hair is going to make a statement. Which means you can pull off an all black or a very minimal outfit and it would still be interesting due to your hair style. The second statement item is the shoes. Then you've got the scarf, and the pearls. I don't think there's a rule on the correct ratio of statement pieces to support acts, I should go look for what Angie says about this. (I think she blogged about it last year.) Also longer ago here.)
I'm a bit torn on the jacket. I really like the shoulder line, and the view from the side in #3 is nice. But from the front I think either a shorter or longer jacket would look best with these types of pants.
