My Dress-Up Darling
This anime romantic comedy follows two high-school students who bond over cosplay, and while it has a genuinely sweet message about self-acceptance and friendship, it is built on a foundation of persistent sexual humor, frequent partial nudity, and fanservice involving teenage characters. The sexual content is woven throughout every episode rather than isolated to a few scenes, making it a firm fit for older teens and adults only.
Older teens and adults comfortable with ecchi-style anime; not suited for children or younger tweens.
Episodes to know about
From the very first episode, the female lead behaves in a flirtatious and sexually suggestive way toward the male lead; sexual humor and innuendo are established as a running feature of the series from the start.
A body-measurement scene runs for a substantial portion of the episode: the female lead undresses to a bikini and there is prolonged focus on her figure while measurements are taken.
A character plays an adult video game off-screen and loud moaning audio is clearly audible.
