Weight 0.8 - 1.0

"SophAlexSC6, blonde hair, low-tied long hair, single braid, blue eyes, silver laurel crown, large breasts, white armored dress, layered clothes, white skirt, cross-laced clothes, pauldron, vambraces, leather belt, thigh boots, leather armor" for her SC6 costume.

"SophiSC4, blonde hair, blue eyes, feather hair ornament, low-tied long hair, single braid, off-shoulder dress, armlet, large breasts, cleavage , jewelry, blue belt, arm guards, legs, gladiator sandals" for her SC4 outfit.

There's a bit of inconsistency with the white dress around her chest, try removing "white skirt" and using "halterneck" if you run into trouble

I heavily recommend using any of her hair accessory prompts ("silver laurel crown", "feather hair ornament") to help with consistency while generating untrained outfits.
