You look very regal in the first dress. And the second dress reminds me of a fairy princess. They both look wonderful. So depending on the vibe your going for is important. To me, I want to feel special and be the hottest girl in the room, so fitted is my favorite. But you look so sweet in the second dress.
They are both beautiful, #2 is my favorite though! I love dresses with sleeves, mine has them too! I’d pick the one you feel most comfortable in, even if the dress is gorgeous you don’t want to be uncomfortable all day. And if you feel uncomfortable it’s going to show in pictures and things.
