Formula Suit (フォーミュラスーツ Fōmyura Sūtsu) is the environmental adaptive protective clothing (環境適応防護服) cast by the Florian sisters in the movie continuity to strengthen body functions and energy interference skills. Such skills can analyse and then invalidate magics.
Furthermore, the Suit also has a drive function to boost one's power output for a short while. Particularly, Kyrie Florian's Formula Suit Type-K is loaded by Iris with an additional System "Alter" (システム「オルタ」 Shisutemu "Oruta"), which can disregard the Suit's limiter and boost Kyrie's powers to extreme, but at the expense of her body.
