Party Outfits to Choose

My friend Sara invited me to the party tomorrow night at her house down the town. I have been looking for party outfits last few day. The outfits in my wardrobe are all used in some other occasions in the past days.  Here is some of the dresses chosen to share with you.

These two dresses are pretty, and I don't know which two choose for the party. And my hand bag is showing below:

This handbag is birthday gift from my husband. And he told me to choose the first dresses here. Maybe I should take his advice.
