BAM, try this. Download the text file attached above, rename it to "Women's Vest 2.cr2" or something similar, and drop it into your Clothing-female folder. Launch Poser and load the new clothing figure.

It's based on the leotard's .cr2. It seems to fix all of the conforming problems, except for that 180 degree weirdness with the hip rotations.

By the way, the 180-degree hip bug seems to occur only when one or more of the Twist/Side-Side/Bend dials are at exactly 180 degrees. And depending upon the values of the three dials, it doesn't always happen. Strange.
