Gwen Spider has eaten a lot of delicious things and understands that it would be better if she did not eat.
The stomach not only digests food, but in the case of a fat belly, it will digest so that the belly mass will go away and be distributed throughout the body, so it is not surprising that her clothes are no longer suitable for a new body.

Although being a sexy woman is also a good idea.

"Damn it, I'm already getting tired of such a fat belly, and now my stomach has begun to distribute the mass of the belly over the body, I need to create a new suit with a rubber fabric!"
