I think number 2. Something someone said to me was they pointed out my body language in the pictures of the two dresses I was debating between! You look more relaxed and enjoying the second dress. It may also depend on the theme and vibe of your wedding which will fit better. They’re both beautiful choices, but I would pick 2!
I actually tried on dress #1! The one I tried was also too big for me, so it didn't look quite right even though I do think it's a gorgeous dress. That being said, dress #2 looks so amazing on you! I love the silhouette style and the v back!
