this lora is mainly based on the popular design under lady pot tag of pixiv.
Meanwhile, actually you can tell that the concept of Pot Girls is not strictly originated from anime--in real world, similar concepts has been emerging for a rather long period already.
For example, in old days China, there is a magic trick called "Girl in the Vase/花瓶姑娘". The circus will be claiming that they have softened the bones of performers with secret recipe and then stuffed them into vase. Meanwhile actually it's just a trick using mirror.
Sometimes, old man will say this to warn disobedient children: "Don't run too fay! Or you will be kidnapped by the circus, and they will cut your limbs and make you a girl in the vase."
