The fact that the fashion was considered
daring in their times suggests that it was something completely new. Of course one might be tempted to choose
revealing as the choice for blank one, but "in their times" indicates that something can be daring without being revealing. Neither can
proposed be a good choice because there is nothing to suggest these styles were proposed by someone.Thus
original is the best choice. And since they have been so widely worn and imitated, it is obvious that the style would no longer be seen as "daring" - so we are looking for a synonym of "daring" and hence
outlandish is the correct answer choice.
The meaning and structure of the sentence demand that both the words for the blanks should be synonyms. We cannot find a synonym pair for
original and
revealing in the answer choices for the second blank.
