This model is quite easy to use, just start your prompt with "a ballet dancer wearing ballet dress", add if you want "wearing tutu" and change the color as you want like "a ballet dancer wearing red ballet dress, wearing yellow tutu".
Keywords "in theater" and "in a studio" might give good results considering its a ballet dress and thats the proper environment for it.
regarding ballet corp keyword, i didn't manage to make it work even if many images of ballet corps dancing were used to train the model, you might give it a try and achieve what i didn't.
