Great, but I do not understand the criticism

Seeing the reviews, I thought strongly take a "risk" in ordering this dress. There are a lot of criticism in the comments, as for the size, quality, etc ... So, I took a size up from mine, and I really thought I went to be disappointed by seeing comments. Only when I received it (very quickly by the way) I was surprised. Product exactly as pictured, the belt is very beautiful, it's fine with me. A bit lengthier against.
But I do not understand all the criticism, because I personally did not find any fault.
To sum up, the dress is beautiful, and fast delivery. Quite cheap and more.
