Formal Wedding Guest Dress

Which one for a formal wedding at a golf club in New Jersey end of July?

Thanks!!

ETA: Wow, thanks everyone for the overwhelming response. I’m going through all the comments and heeding everyone’s tips, tricks, and advice. Some people asked where I got the dresses from:

#1: Park and Fifth Co. It is the Roslin dress in pitaschio green. I love this dress, however, it does run pretty small. I ordered my regular size and had it tailored already. The tailor let out some of the dress on the chest and the waist. I love the comments saying I look like a Greek goddess! That may be going to my head! 😆

#2: I got real lucky with this one. It came from a secondhand consignment shop and was already tailored to perfection. I do have reservations about the color being more Fall/Winter, but the saleswoman convinced me to get it. It was the cheapest of the 3! The brand is Betsy Adam.

#3: The brand is Reformation. I got it off of Poshmark. This was supposed to be my dress for a wedding last year, but I wore another one. I had this dress tailored. I may have gained a little weight in between last year and now, so it’s a little more form-fitting.
