That's a tough one I would probably say Vicki because she has both huge boobs and a big butt so that increases the odds of something going wrong, plus Vicki for the most part cant afford new clothes so I think she wears them out until their either too small or they rip. Lisa wears stretchier cloths and probably has more options despite her sheer size so I think Vicki is more likely to have he clothes malfunction if that makes sense.
