What does one wear to an Anthro Opening Event? Reader Poll!

I have a quite fun event coming up this weekend, and I wouldn't mind some help choosing an outfit! This is actually me asking for help because I can't make up my mind, and need someone to say "Jess, wear that".

I did manage to narrow the selection down to 5 dresses, paired with the same jacket and boots.

Outfit #1

Anthropologie Golden Lights dress

 Outfit #2

 Hayden Harnett Yoko dress

Outfit #3

 Diane von Furstenberg Zora dress

Outfit #4

 Anthropologie Zachary's Smile printed dress

Outfit #5

 Hayden Harnett Helena wrap dress in the Painterly print

I would love some input, so please help me choose with the poll on the side! It is supposed to rain, so boots are needed for me.

Thanks a bunch :)
