Jacqueline is the main antagonist in Barbie: A Fashion Fairytale. Jacqueline owns a fashion house in Paris, Jacqueline's, where she works with her assistant Delphine. Barbie Roberts came to Paris to see Millicent, who is her Aunt. Delphine and Jacqueline saw Barbie while she was walking around Paris, and Delphine told Barbie that Jacqueline had ruined Millicent's. Millicent had given up on designing because the news press only paid attention to her to insult her. However, Barbie and Millicent's assistant, Marie-Alecia, found the flairies, three magical beings who could use magic to improve fashion designs. With the flairies, they improved the designs at Millicent's so they could stop the fashion house from selling. Jacqueline spied on Millicent's and she watched as the flairies glitterized Marie-Alecia's dress. She knew she had to do something before Millicent became famous. Later that night, when Marie-Alecia and Barbie were out to buy fabrics, Jacqueline and Delphine crept into the fashion house and kidnapped the flairies. Jacqueline ordered the flairies to improve her line of clothes but the flairies weren't inspired by their clothes and they warned Jacqueline and Delphine that they weren't inspired and something bad could happen if they glitterized the dresses, but she did not believe them. Delphine started to spray cheap perfume at them until they gave in and improved her designs. On Sunday night, Jilliana, Jacques, and Sequin, Millicent's and Barbie's pets, see fireworks that the flairies made and they rescue them. On the day of Jacqueline's fashion show, Lilliana Roxelle had attended the show, so Delphine and Jacqueline were very happy. Delphine wished Jacqueline luck and Jacquline went to introduce the show. Everyone was excited until the beauty the flairies had given the outfits began to fade away. The clothes began to smell like gym socks and the designs turned into garbage. Lilliana left the show and went to Millicent's show instead. Delphine and Jacqueline also watched the show, and so Jacqueline apologized for the way she had treated Millicent. She also apologized to the flairies for kidnapping them. Millicent said she forgave them, and that they could all work together someday.
