I'm all for more options to customize your WoL with but at the same time, I'm not particularly a big fan of item that morph your dimensions to the extent like the 2B Bottoms do.
I'm not sure why anyone would want this route anyway on the basis of it restricting your options more than expanding it. If your ideal WoL has to be thicc, then you have a very narrow selection to represent them with and let's be honest, if more were to be added it wouldn't be at a rate that you wouldn't feel the restriction.
Character model morphing should be done, specifically, at the creator and the dimensions you select for your character should be done then and there. If I were to equip Minfillia's attire, my boobs shouldn't shoot up 3 cups. Amusing, comical, perverted, whatever you want to call it - that's not the boob size I chose in my creator and in the event I chose the max size I shouldn't have to wear this outfit to get it larger.
I understand this may be a small and niche complaint, but I'd rather the in-game textures reflect the decisions I made in the creator and that the creator offer more (butt slider, better muscle definition, body hair on females, etc.). I'm well aware of the difficulty and how much this sort of task ripples outward but the longer this sort of thing is put off the harder it's going to be down the line. Tackling the creator SOONER will be easier on the development team, if I understood their explanation on item creation in the game.
Lastly, I'm not a fan of things like boob plate or items morphing based on the WoL sex, such as: The belly window of the Dragoon armor, pants becoming pencil skirts, shorts becoming panties, etc. I'm not advocating for these to be removed but for those of us that don't appreciate that style and are looking for what the item thumbnail offers or don't appreciate the faults in armor design when they don't exist for the opposite sex, to be able to toggle between the two.
