This LORA aims to help an AI Art prompter to generate quality images for fine looking women who are either wearing shirts (fully clothed SFW images) or are undressing and removing their shirts ( Images with full or partial nudity, NSFW images). While keywords usage is not be absolutely necessary ( quality of your results will increase with proper descriptions in natural language ), you may use these keywords to gain proper aesthetics for your subjects -

Female_In_Shirt, buttoned, fully dressed - will most likely generate SFW output

Female_In_Shirt, unbuttoned, undressing - will generate NSFW output

Just note that this LORA, although not exclusively intended to produce NSFW images, too often may produce NSFW outputs so you have to fine tune your prompt little bit to get your desired SFW output.
