Greetings ! I am Clémentine ‘Clem’ Gelly, also known as “arborealkey”, a 27-year-old artist from Marseille, France.
After making costumes as a hobby for four years, I went full time in early 2019. I constantly seek improvement and always look forward to trying new techniques.
Despite starting as a cosplayer, reproducing existing content, I have grown to enjoy designing costumes as much as copying them.

Here are a few of the things I can do:

  • Costume & prop construction
  • Costume & prop design
  • Trophy design and fabrication
  • Promotion in costume
  • Tutorials & patterns

Want to commission something ? Please write to contact@arborealkey.com. You can see past projects here or download my portfolio here.
