Lea is a rather fashionable individual, as her interest in fashion is shown several times - she was impressed that Regina George has two Fendi purses and a silver Lexus. Later, for the Halloween Party, she dressed as a Playboy Bunny.
In an iconic scene, Lea wore a 'vintage' skirt that was her mom's in the '80s, with Regina saying that it looks adorable. However, as soon as Lea turned, Regina stated that it's 'the ugliest effing skirt she has ever seen'.
While Lea's character wasn't deeply explored in the movie, she can easily be described as a nice person, since she always has a smile on her face when talking to other students. However, judging from her reaction when her hair was getting soaked by a sprinkler, she can also be described as a drama queen. She has also shown to dislike Cady Heron and would give her weird looks as she passes by and instead, adores Regina George.
