Appearance

Base

elsa granhilte, black hair, purple eyes,

Dress

assassin outfit, a black dress with purple trim and deep open front, detached sleeves with purple frilled cuffs, brown pantyhose, black heels, and a long dark red-lined hooded cape with a gold clasp, a purple rose in her hair,

You don't have to describe the entire outfit or her looks every time, it does understand what the assassin outfit is and her general appearance from her name - and you can remove pieces of the outfit such as the cape - but I would advice you do enforce it a bit with more info like above.

Enjoy + leave a like! :D
