they are jenny’s alternate looks, the first one is simply her feather to the side in her ear instead of being in front of her face, the second outfit is from her alter ego “Lone Lady”.

Notes:
Well, I Liked The Feather, But I Just Guess It Might Be Hard To See It For Her.
I Like Her Mask Although I Wait For Comments About The Design.
