A Hi Lo Gown Model I created unreleased, merged with LucentDream (https://civitai.com/models/264855/lucent-dream-or-luminescent-dresses) I tried to create a fashion similar to the November Rain wedding dress, and train from that, and It went off the rails from there. This Lora FEEDS on your over the top prompting. Fantasy is it's first, second and third course. This one goes especially hard on Latent upscale Seraphelle, but you might have your own fantasy/illustrative model to try, like ZovyaRPG, or Dreamshaper .
The Hi Lo is a more illustrative style, and is trained on tall, elaborate headpieces/crowns as well. Because of the fantastical nature of this training, Pure photography or hyperrealism is not recommended. It would be missing the point, but I wont stop you from trying!
Heres the catch with this one. It's sort of overtrained on a standing pose, so your poses need to be more deliberate. (dynamic pose, hand on hips, etc) should get you there. It's almost a style and pose within a lora, but it's still a HiLo Gown first and foremost
Flip it to 768x568 for closeups usually and you'll get some pretty great stuff too.

Again, this this feeds on over the top - unique, exotic, wonderful, met gala, (screengrab from <over the top movie>) pay out on this one, if you use the right model.
