They were able to share a bit of concept art and their thoughts on the piece with us, so what follows is their own words.
The Experiment House uniforms are probably the last thing you’d think about while imagining the costumes for the upcoming film. The Silver Chair film brings to mind the gorgeous green gown worn by the Lady of the Green Kirtle, the lovely yet comfortable clothes donned by Jill and Eustace upon their arrival to Narnia, but never the dull, uncomfortable and surely boring uniforms of the horrid Experiment House where Pole and Scrubb attend school. This is why, when we were asked to submit our ideas and thoughts for the uniforms, we were delighted. We wanted to turn something mundane into something that would add depth to the characters, in particular, Jill.
The Experiment House uniforms would be the typical British boarding school uniforms of that period—scratchy skirts, shorts, slacks, blouses and blazers, with the occasional sweater or two—nothing unexpected. We wanted to give Jill a bit of flair…not to be the most fashion-forward of the school, but to have a special style in her own way. Perhaps the reason she is picked on by the bullies of the school is not only because of her rather strange last name, but also because of her unusual way of dressing?
We were inspired by modern films, typical schoolgirls of today, and TV shows like Gossip Girl. Today’s schoolgirl who is inflicted with a strict dress code or school uniform wants to be as unique as possible. Jill is of course her own person—she doesn’t like being told what to do, or how to do it. And what better way to get this message across in the film then by her outfits?
Her red/grey uniform is accessorized with colored knee-highs, bright tennis shoes, and a beret. She changes up her blazer by belting it, and has a unique cross-body bag. We feel that this costume helps bring out Jill’s best qualities to the audience, and will make them even more eager to sympathize with her. We’re very excited to see the finished product in the opening of The Silver Chair film!
So are we! I'm sure the Tallon and Tanival duo have something spectacular up their sleeves for the rest of the film!
Waaayyy too modern. And they were inspired by
