Princess Kathleen is one of the major characters in the 2006 animated film, Barbie in the 12 Dancing Princesses. Her parents are King Randolph and Queen Isabella, and they have twelve daughters. Kathleen is the triplet of Janessa and Lacey, and they are the three youngest daughters at only eight years old.
Kathleen is the second youngest in the family. Often giggling with her triplet sisters, Kathleen is a happy little girl. She and her sisters were described in the movie as "rambunctious". Like all of her sisters, even though they are each different, Kathleen loves to dance.
Unknowingly, Kathleen does not always take other people's feelings into consideration: she ignores her father when she hears she can get new shoes, and she and sister Janessa often leave Lacey behind without realizing or remembering her. Kathleen is calmer than Janessa, but braver than Lacey.
Kathleen enjoys painting (and often gets messy, as she had paint in her hair at one point). Kathleen is closest to her sister Janessa. Like most children, Kathleen is easily entertained, as she was amazed by a bug she and her triplet sisters had found.
Kathleen has fair skin, long red-orange hair and blue eyes. She is identical to Janessa and Lacey and wears the same style of dress as them, which is a short sleeved gown.
The top part of Kathleen's day dress is light pink and the sleeves are short and puffy. There is a band around her waist with a pink flower on it, and her skirt is yellow. She wears white tights and pink dancing shoes so she can dance with her sisters. Kathleen wears the same nightdress as all of her sisters. It is long and white with long sleeves and it is floaty.
Rowena makes Kathleen and her sisters wear a gray dress. She also has to wear her hair in a bun with a gray band. As all the sisters look the same, their individuality is taken away from them. Kathleen's ballet dress is like her day dress, but shorter. She wears her hair in a bun with a Lilac band with this dress.
When Kathleen is the bridesmaid for Genevieve and Derek's wedding, her dress is similar to her day dress but the colors are different. She has her hair out and the dress is white at the top. The skirt is very pale yellow and her dance shoes are white.
