An Illustrious embedding of a brown haired woman. The default features show consistently without added prompting but here they are just in case:

brown hair, wavy hair, long hair, side part, pale skin, thin body, wide hips, eyeliner, brown eyes,

While lovely and consistent by itself, embeddings really shine when combined with LORAs allowing different looks and adding consistency.

Note: this does not portray any real person, living or dead.
