In my experience, Krea2 doesn't really need anything other than the main trigger word when there is only one outfit. Are you having trouble with the outfit on this one? If turning the weight of the LoRA up doesn't help them I can add some tags. Also try using the trigger word several times in the prompt. I have noticed that when you use pronouns like "he" or "she" more than the trigger word, Krea2 will sometimes try to draw a more generic character
