Oh, I now see why some people thought I had a strange idea about the NGM's for the outfit. I thought I had originally mentioned the Petite ones for V4. Here's a comparison against the GND ones.

Can you see what I originally had in mind? It wasn't the larger boobs, but the smaller ones for the smaller frame.
I understand these don't work too well with the GND4 (I'll test just to confirm it to myself) but on V4 & A4 they look great.
