Depending on the movements of the model, the skin may jump out over the clothes.
If this happens, please erase the parts of the skin texture appearing over the clothes.
Select Body Editor > Texture > ▼Skin > Default Image and erase the parts of the skin texture jumping out over the clothes.
As you requested, in this version upgrade we added the missing skin under the uniform.
By erasing the texture, you can make skin invisible as you would do with clothes. If skin jumps out of a character's clothes when moving it, please try erasing the extra skin texture. The sample model Sendagaya Shibu has a part of her skin texture erased.
