Does PWizard remove the preset bends from the figure that it is using as a base? To find out, select your new dress in the image above, open the Joint Editor and hit "Zero Figure". If it now aligns then it didn't so you must now go to Edit/Memorize/figure and save it back to the library.

Also does your dress include a neck and head? Not as actual mesh but as elements within the CR2. Although missing heads tend to result in a skew sideways I thought I'd ask just in case.

Finally, again to get more info, how have you grouped the lower portion of the dress?
