If you used an existing figure CR2 its probable that it has preset bends in it. The solution is as follows. Load your clothing, and turn off all IK chains. Now open the joint editor and click on the Zero Figure button. Next select the hip and ensure that the x, y & zTrans are all zero. Repeat for the body. Now go to Edit/Memorize and select figure. You have now removed all the preset bends. Save your clothing back to the library.

There may be other issues but try this first then we can take it from there.
