Hey everyone! I have a couple scars in the middle of my back from acne, and unfortunately the back of my dress isn't high enough to cover them. Do you think my seamstress can add fabric to heighten the back of it (1 or 2 inches) into more of a straight-top back? I will have some extra fabric because the dress is really long on me (I don't know if that will be helpful at all). Thanks

Here is a picture of the back of my dress:
