[ISSUE] Need information about new body BHUNP and outfits converted.

[Firch50]

Hello everyone, I have an issue with my outfits and the new body BHUNP...

I installed this body, and downloaded some outfits converted to BHUNP (by Baka, the creator of BHUNP) to try it out, but when I wear one of these, my character body shrinks slightly, especially thighs, butt and hips, and very slighlty for boobs.

The thing is I ran bodyslide and Batched build with the same preset for all of my outfits, so basically, I should have the same body shape for all of my outfit, but when I wear particular outfits (not all of them), body shrinks... Does anyone knows how to fix it please ? 

I precise that I did like Baka said to do for each outfit, so when the conversion needed the original file, I installed the original file, then the bodyslide conversion of the outfit.

PS:  I attach Screenshots to do a comparison between nude and outfit body shape.

 

You can easily see the comparison by pressing the scroll button of the mouse on each pics, and navigate through the pictures.
