The LoRA was trained with around 35 photos, many of them of dancers, so do be surprised if you get the occasional weird pose. Both "open front skirt" and "open_front_skirt" seem to work as triggers.

The open half skirt is a clothing item generally worn by dancers, serving a similar role to a bustle. None of the checkpoints I tried seemed to have this as a concept, so I made a quick LoRA for it. All of the images in the showcase post are just "picture of a woman wearing a (color) open_front_skirt," so you can see how it tends to default. I've tested this on a variety of checkpoints, and while most generally play well with it, a few simply ignored it no matter what I tried.

One final thought: Some of the source images had platform shoes and high heeled boots (it's a look, I guess), so if you're wondering why your character suddenly has combat boots on, that's probably why.
