Her invisible limbs rely on the Hide Skin by Mask plugin by @Hunting-Succubus . This is not included in the VAR due to NC status.
Add the plugin to Tasque's model and only enable the LimbsMask. Next, go to the Clothing section and choose to customize the Hide Skin clothing and select the LimbsMask option. Go to Textures and choose Select next to the "_AlphaTex" option. The Alpha texture can be found in the Tasque VAR file under /Custom/Atom/Person/Textures/Sivel/Furries/Tasque/Alpha (phew!). You can also just extract it and place it in a different folder that's easier to access, too.
