A concept of long legs in high heels.
Version v0.1 is a LyCORIS/LoHA.
Version lora_v0.1 is a Lora (civitai shows a wrong type LyCORIS).
This new trained Lora version of the v0.1 (LoHA) was a request.
It seems that the Lora performs a little worse than the LoHA version.
So you may should better use the LoHA v0.1 version.
