Look at that reference image... I don't quite understand how the fur is attached. Is it just draped over the shoulders like a shawl? And should we put something on over the dress, like... how do you call that sleeveless black thing that goes between the dress and the fur?
P.S. How did you want to test the model's functionality?
I don't think the sleeveless vest is necessary, but we need to see what comes next. Maybe the fur will be aristocratic enough on its own, or maybe, on the contrary, it won't look like the clothing of a wealthy person, but rather a gloomy, ascetic priestess... No, the priestess should be wearing a hood, so let's go with an aristocratic sorceress.
To test the functionality, just load the static model into the game. If it loads, that's great, and we can continue working. Hmm, I'm a little worried. I abandoned my old RTF project because the model was too large and overloaded the memory. Since then, I've been releasing all units separately so that the mod can be rebuilt from scratch.

Here's how it looks with the fur and boots.
