genius
Explanation
This comic features a female superhero who tells a tailor she needs to "fight villains all day" but also wants to attract "uncomplicated casual encounters." The tailor says "Say no more."
In the final panel, labeled "Later...", the superhero is wearing a costume with a prominent chest window (boob window) and declares "These things are GENIUS" -- referring to the costume modifications.
The joke comments on the long-standing trope in superhero comics where female heroes wear impractical, sexualized costumes. The humor comes from flipping the usual framing: instead of the costume being designed by a (presumably male) artist for the audience's benefit, the character herself actively chooses the revealing outfit for her own practical romantic purposes. It's a tongue-in-cheek acknowledgment of the "boob window" trope (most famously associated with Power Girl) while giving the character agency in the decision, which makes the whole thing funnier by removing the usual criticism and replacing it with enthusiastic endorsement from the wearer herself.
