Breast Envy stems from the belief that "bigger is better" when it comes to a woman's breasts. Women with smaller breasts sometimes become envious, jealous, upset (or a combination of the three) towards those with larger breasts.
Anime & Manga
One of many recurring tropes of anime and manga, Breast Envy usually takes place when one female character comes across another with much larger breasts than they have. This usually results in the first character becoming jealous and envious of the other due to the fact that their breasts are much larger than theirs and thus, they are more likely to attract the attention of men, who often seem to have a weakness for busty women.
Most examples of this tend to be found in ecchi/harem-themed anime and manga, in which several female characters are vying for the love and attention of one male character. Fearing that they will be ignored or looked down upon since they do not have the large breasts of the other characters, the characters with smaller breasts grow envious of their busty competition and tend to go to great lengths in order to get attention from the male character in question.
- In Manyuu Hikenchou, Kaede becomes increasingly envious and jealous of Chifusa Manyuu's ever-increasing bust size, adding to the frustration of having her own breasts shrunk down early in the anime.
- In Sekirei, Benitsubasa shows frequent breast envy towards the many buxom main characters. She insists that her smaller breasts are better, though it's made clear that she's extremely jealous.
- In The Familiar of Zero, Louise is envious of virtually every female character around her. Both herself and the busty Siesta show particular breast envy towards Tiffania, who dwarfs them both.
- In K-ON! during their first trip to the beach together, both Yui and Ritsu show strong envy towards Mio after noticing her large breasts in her bikini. Ritsu even throws a beach ball at her face.
- In Heaven's Lost Property, Angeloid Nymph has a very flat chest, while every other of her fellow Angeloids in the franchise has rather large breasts. She becomes envious of the large-breasted female characters since it seems to attract the perverted attention of Tomoki Sakurai.
