I really need to know what to expect with alterations...i.e, how much it will cost and what the process is like...I bought an amazing dress because the manager of this salon gave me an offer I could not refuse on a brand new sample. OK, so it's a size 10 and I am a street size 2-4. That means, basically, the bust and waist need to be majorly taken in. However, the length is perfect, because it's long enough (I'm 5'9"). I will also need a bustle. Does anyone have any idea what this will come out to? I want to be prepared! Thanks...
