That's not mutually exclusive?
Not that she is as wild as Ivy or Jess, but that wasn't suggested, either. She was introduced as the hot taken girlfriend, just a bit opinionated and spoiled.
There are some hints that she is a bit naive and easygoing, but she is too sharp, stubborn, observant, emphatic (if she chooses to be) to pass as the stereotypical brainless airhead blonde.
Her looks play into it for sure, but her plotline was a well done slow burn and quite intriguing. Currently it stalls and has lost it magic.
