I say go for it. This is hobby of daring and adventure so if Galados wants to be Edwardian, she can be Edwardian. (And now I am hearing her yelling 'C'mon dover!" is that creepy voice she has...)
Love the parasol idea as well. As for the skirt, were looking at the.... triangular shapey skirt? Not that familiar with Edwardian...but like this? http://www.trulyvictorian.net/tvxcar...&cat=14&page=1
And then adding wires around it? Or having a skirt like that as an underskirt and then a bustle or overskirting at the back and connecting the wires to that wrapping around to the front, almost like a cage bustle but on the top of the garment? (Though...bustles are more Victorian Era aren't they)
Either way, love the concept.
