Without looking I very much doubt this is in any way related to the Atelier series.
For the non-weebs... In anime circles when one speaks of Atelier, they're generally referring to the LOOOONG running series of games by Gust (now part of Koei Tecmo) that began on the PS1 with Atelier Marie: Alchemist of Salburg, an RPG in the mold of early FF or SO but with a bit more crafting emphasis. Generally speaking, Atelier games are what you'd expect of JRPGs, although the original's premise was fun (the OG Marie being a magic school flunk out alcoholic on academic probation).

Looks like it's being used in its modern context where it refers specifically to fashion designers. Thus the hats.
Regardless, it's the pronouns in bio and race shit, not her work, they're talking about.
