I'm going to try to answer,
well mmm I think evening gowns can suit her, I don't know if you remember this editorial for Vogue Paris; she wears beautiful gowns and in one of the pics she throws coca cola. well this is one of my favorite.
But in this one it doesn't suit her at all -It's not the same style-, she has very strong features and an insanely gorgeous body but also very muscular and, to me at least, Daria is the epitome of a very sporty energic woman she suits perfectly Isabel Marant's style for example (thats just an example among many)
for those pics I'd prefered someone with a softer face...
It looks kinda weird with her its as if there was a contrast between her and the dresses, maybe it was made on purpose though ? I don't know.
hope it answered
