Truth is that WB/Jany (costume Designer) did much better job with that dress than Alexander McQueen. da the way, people will probably like Fleur's dress and if they associate it with Alexander McQueen that'll do only good to him. Some free advertisement never hurts, does it?
I think it's the lenght of the dress itself, of the black part and the color too. Looks a little less birdish. But that seems too much like a winter wedding dress because of the top, is it just me?
