It's a lovely dress and I'm sure your daughter would look lovely in it, but I have to agree with previous posters- it's really not appropriate for the situation at hand. It's far too short, and a "tunic and leggings" look, while cute and trendy, is not appropriate for a formal occasion like an evening wedding. Also, unless it comes in other colors, the white at the wedding would be a problem, too. As pretty as the dress is, I really feel that it's far more suited to, say, a night out on the town, rather than a wedding.
