I have been trying on wedding dresses and I have heard that they are not always true to size. One store said I would need about a 10, however when I look at the designers size chart the bust on a 10 is a 36.5 Mine is only a 33, is this a pretty normal allteration? the dress I am looking at is Mori Lee 1601 so there isn't a lot of detail on the top. has anyone had a bust alteration similar?
