Tomorrow I tell you in detail not in pc anymore lol. but first you need hololive dance outfit lora, and the Mona one 

 Model mm is more up to you but if want the same style then yesmix, the prompt itself is just technically remove her clothes and add the others from the holo one easy lol. 

 Proof of prompt. Also if you insert positive prompt like that without having the loras the model barely will do nothing with the character or the outfit since is specifically trained for example aamona word is a trigger word for Mona, there's model that has in their database characters but not all so you need to use external loras.

 In negative prompt there's some embeddings so more files to download (badhandv4), verybadimagenegative_v1.3, ng_deepnegative_v1_75t, DeepNegative are. the rest can be copy without any issues and can be used in other models since is negative but beware some models don't like to have so many words in negative to produce good results.
