I love the dress. I really wanted a dress with cap sleeves so I'm kinda biased that way . I really don't think it's too much because like Kim said, you'll be on the terrace. Plus, it's your wedding and you can wear anything you'd like . I think whether you decide to keep it like this or take out one layer from underneath it will look great.
I like the first and the third inserts the best. I think the first is nice, simple and clear, but the third one is also nice with the picture. Another thing to consider is that if you're printing them at home maybe the first one might come out better. Sometimes, unless you have a super nice printer it's hard for the pictures to come out really sharp.
