Base: Ninian

Default appearance: ninidress, detached sleeves, shawl, asymmetrical sleeves

Bridal Bloom: ninibride, wedding dress, bridal veil, white clothes

Add "long hair, red eyes, blue hair" if needed but her appearance should be baked in. I tagged her dragonstone as "blue stone". I tagged her snowflake belt design in Fire Emblem Heroes as "Snowflake_Belt". Her sleeves in her original design are asymmetrical, but you can leave it out if it causes problems. Some elements of the outfits might bleed into each other.
