>>7547832Here is a thought I had, instead of slime stuff, what about another material?
In this case I am looking at Mold making stuff.
the first contender that will likely be the best for you is Blu Stuff, a reusable mold material. You put it in hot water to make it malleable and it hardens enough to retain a shape complete with tiny details good enough to use for making duplicate parts of models and yet is still flexible enough to allow you to remove the items easily.
Also the obvious is it is blue and translucent which is a bonus for your goal. how well it works for sculpting I got no clue. Have not used it myself yet so can't do any testing. I still use typical silicone.

The problem with it though is as far as I am away the only Silicone Mold PUTTIES are all opaque and thus not good for this. This means you have to utilize a liquid silicone mold compund, which obviously will make directly sculpting it impossible. You will have to sculpt the girl out of clay or some kind of epoxy modeling putty first, then make a mold for that, and then proceed to fill that mold with your clear liquid mold. There is the risk of course of the release agent failing to cover every surface and elements of the silicone figure fuses with the silicone mold making removal terrifying.
But the one good thing of this method would be you can make any color slime girl you want by adding a drop or two of food dye to the liquid silicone.
Personally I would give the Blu Stuff a shot first. afterall, it is REUSABLE, so if you screw up, try and try again.
A last second addition to this, when looking up prices, i found Japan has alternate colors of this it seems called Oyumaru.
