Hello and welcome!
I think of the three that you have there, the middle most fits with the idea and with a touch of villainy.
However, the outfits that you have there do not really remind me of the victorian period. I always think of it as having really absurdly useless clothes. Now you might want to subvert that concept and have her directly opposed to any victorian stylings, which is great.
But if you are interested, this link http://2.bp.blogspot.com/-bMr5BfGK61U/TafOMugjyGI/AAAAAAAAAms/tFVvqm3Z9HU/s1600/1880-09+Petersons+fashion+plate.jpg has some interesting dresses in the image that look somewhat sinister compared to the normal victorian fair.
Anyways keep at it! I look forward to seeing what you do with this concept.
