I think I've narrowed it down to two! I tried on a ton of dresses and these are the two that I just kept coming back to. I know this isn't a picture of me in the dress, and indeed, it does look completely different on me (I feel like the models look awkward). However, I thought I'd ask what you ladies thought of these two dresses:
Dress 1:

Dress 2:

Just some background info: the wedding will be at the Schlitz-Audubon, the ceremony will be outside and the reception will be inside but there will be an outdoor space for guests to socialize as well. During the ceremony, I will be walking down a runner covered in rose petals by lake Michigan. The wedding will also be in in the summer, I'm allergic to the sun, and heat bothers me, so I want a very comfortable and light weight dress.
Thanks ladies!
