"This is the first LORA with more than 10 outfits I make, so any feedback would be appreciated!"
Welcome to the club! These are exhausting to make, but good fun and satisfy my completionism. Did you use multiple shuffle tags+keep tokens for this (with main trigger first tag and outfit tag the second tag)? I like to do this when I've got loads of outfits but no idea how much (if any) impact it actually has.

BEAUTIFUL 😍😍😍

Hello. I have some experience with training Loras with many costumes (never posted any, but I might in the near future).

Even if you separate each costume by a base trigger tag, i'm sure you noticed that the AI still gets confused and tends to mix some details from different costumes. My main advice to resolve this, is to do your best to not repeat tags between costumes.

In this lora for example there are many dress pieces and in my quick testing the AI was mixing some details. so instead of just using " X color dress", it's best to think that each costume piece needs a base tag that the AI will use to identify it's general format.
"Long dress", "short dress", “single-shoulder dress”,“layered dress”,“dress straps”,“halter dress”, "pleated dress", "evening gown", "open dress", "coat dress" and many many more. Danbooru wiki is your best friend, if you type "dress" there for example, it will show you a page with all possible tag variations on the site and you can click on them to see explanations and examples. Use those to decide which tag looks the most fitting for each specific costume and try not to re use them in the same lora.

Also if there are multiple costumes with similar details, there are ways to describe them using different tags if you're creative enough. If you have 2 dresses with frills, you can use "frilled dress" for one and be a bit more descriptive with the other, like: "one-piece dress, short skirt, frilled skirt/frilledtop/frilled middle", and maybe if there is a third costume with frills, you can just say "frills" as a separate tag, as long as you don't re use the same tag the AI will sort itself out most of the time.

Just one more example, let's say there are 2 costumes with jeans, wel you can use “denim pants” in one and “jeans” on the other. and so on.

Sorry for the long post, but I really hope this helps. Making these oras is a lot of work, very exaustive, but also very rewarding when it finally works and correctly tagging the training data is frankly 80% of the job. Anyway your lora really helped me this time so keep it up.
