they give me steampunk vibes, so I'm thinking corset, oversized ruffled Victorian skirt (maybe in browns, burgundy, or aubergine) ... basically dressed like Helena Bonham Carter in Sweeney Todd.
The shoes are too "out there", it encourages crazy, theatrical outfits π
EDIT: and I would never spend $300 for these shoes, and even if they were free I'm not sure I would ever wear them (but I would probably find a single occasion to go all out and honor the shoes with a full outfit, then they spend the rest of their lives in a closet).
