Ana - Medusa (lancer) from FGO, lora is based on game arts, anime screencaps/arts and fanarts, so there will not be a full replication of the style from the Fate franchise.
Main trigger word is simply "Ana", tags like "Hoodie", or "Headband" will add mentioned outfit parts, if you don't want them i suggest putting them into negative prompt.
Sometimes clothing prompt tempts to change her face a bit, or makes her a bit more older, if it occurs, then i suggest lowering power of clothing keyword
(Illustrious version was trained on bigger amount of Ana illustrations than Pony/SD1.5 version)
