The way they draw them feels more of a difference than that, especially in some of the vore/insertion scenes (Like Diula's). Character sheets leave a lot to be desired as you mention in terms of weight. (Never really scrutinized the character sheets tbh). MC comes across as being either marginally bigger at best or somewhat smaller than a finger for them in most cases, and thinner than said fingers to boot.I calculated that giantesses in their "normal" are 15,6 times bigger than regular women, so it will be around 6.41% of their size. If being really precise, Nyxmay for example is 25.58 m. If MC is 1.8 m then it will be 7.04%
Why am I even counting that? The lack of update is driving me crazy.
My point is that clothing entrapment would be unaware or careless/sadistic, rather than splitting hairs about the exact specific size, which seem malleable at best at times with how MC is drawn in relation to them...
