September may be the biggest time for fashion upheaval, with new trends emerging from both street style and fashion month, except when it comes to athleisure. Those new styles and trends tend to pop out in January, right alongside a refreshed interest in building a new wellness routine. And while there’s definitely a wave of new athleisure trends you’re welcome to try in 2025—layered tops, half-zip pullovers, cargo sweatpants—I for one am only interested in embracing Trunchbull Core.
Never in all my years did I expect Agatha Trunchbull, the cruel headmistress in Roald Dahl’s beloved children’s book Matilda, to be someone I’d want to emulate. As an educator, Miss Trunchbull is a literal nightmare and honestly should never be allowed near children in any capacity. But as an athlete, there’s no denying she’s put in the work—she did compete at the 1972 Summer Olympics, after all. And as it turns out she has at least one admirable quality I’m interested in copying: a no-nonsense approach to workout apparel.
