>>25006651Maybe controversial opinion, but I think the correct response is that it's subjective. For example, if that
>>25007703 says is true, I'd say Aoi has the sexiest panties. Simple, monocolour underwear is hot as hell, assuming it's still colourful and not just beige.
Unlike that anon, I don't find lacy underwear very attractive on a woman, nor would I find dinosaur underwear attractive at all. But imagining Aoi standing before me in a baby-blue set of plain lingerie, or even white, or pink, or light-green? Diamonds.
Even disregarding preferences among individuals, I would find the same set of lingerie far more appealing on Aoi than on Iku, simply due to how much more I like Aoi overall. As such, the wearer likely matters more than the clothing actually in use.
