characters were modelled on celebrities popular at the turn of the 21st century. In a 2011 interview with IO Donna, Straffi stated that Britney Spears served as an inspiration for Bloom, Cameron Diaz for Stella, Jennifer Lopez for Flora, Pink for Tecna, Lucy Liu for Musa, and Beyoncé for Aisha. This approach was part of Straffi's aim for the fairies to represent "the women of today." A team of specialized artists designs the characters' expressions and outfits for each season. About 20 tables of expressions and positions from all angles are drawn for each character. The designers start to develop characters' costumes by creating collages from magazine clippings of recent fashion trends. Using these as references, they draw multiple outfits for each character. Simone Borselli, the series' art director, designed most of the characters' early-season clothing despite lacking a background in fashion design. When asked by an interviewer where his fashion intuition came from, Borselli responded, "From being gay." Writing and animation The first stage in the production of an episode is developing its script, a process that can last 5–6 months. When the series began production, the writers were based entirely in Italy. After Viacom became a co-owner of Rainbow in 2011, Rainbow's group of 30 writers began collaborating with teams in both Italy and the United States. The international coordination, which has continued through 2019, intends to make scenarios depicted in the program multicultural and accessible to viewers from different countries. Episodes are written with two stories in mind: a longer narrative arc that lasts for tens of episodes and a subplot that concludes at the end of the 22-minute runtime. This episode structure was modelled on those of teen dramas and American comics. Themes written into the series include romance, the acquisition of maturity upon reaching adulthood, and (in the fifth season) nature conservation. After the script and character designs have been approved, the screenplay is passed onto a group of storyboard artists. For each 22-minute episode, the artists prepare 450 pages of storyboards which are used to assemble an animatic. At this stage, dialogue and music are added to determine the length of each scene. In the original series (seasons 1–4), the characters' mouths were animated to match the Italian voice actors' lines; in the revived series, the mouth movements were matched to the English scripts. Episodes are worked on concurrently because each requires around two
