The limit of the Willing Suspension of Disbelief for a given element is directly proportional to how pretty or stylish it is.
How does a fancy dress
work underwater? Um... It's pretty. That's how!
Basically this is about making things look as appealing as poss... no as appealing as you feel like, no matter how impossible.
Want a castle made of solid pink diamond for your webcomic? Who cares about the cost, or if it's even possible to make that kind of structure. It looks pretty. Or more realistically, the royal crowns and capes. They are expensive and heavy, but they give the impression of majesty. As long as it looks good, the logistics don't matter.
Works made for young girls can be very prone to this (as seen in the page picture), but it also occurs in works for boys, just that the form is different.
But for this rule, not only does something have to be sufficiently glamorous to work, the viewers actually have to want to watch such things. If not, even realistic examples of such elements can turn them off. So this is an audience specific rule.
Note that tropes about glamour, but are perfectly reasonable, are already listed on The Beautiful Tropes
- Adaptational Attractiveness: Characters that objectively look different in adaptations.
- Battle Ballgown: An armored dress would rarely work well as armor or a dress.
- The Beautiful Elite: Unattractive people somehow don't exist, or are extremely rare.
- Beauty Is Never Tarnished: No matter how much someone should be covered with dirt and bruises, it doesn't happen.
- Bishie Sparkle: Sparkles don't just appear around attractive people, or people (usually) don't just see sparkles around people they think are attractive.
- Ermine Cape Effect: Royal crowns, robes, and ermine are not practical to wear all the time.
- Everything's Better With Sparkles: For the instances where things sparkle for no clear reason.
- Frilly Upgrade: A Magical Girl outfit somehow gets more fancy as the girl gets more power.
- Frills of Justice: Not that magical girls are realistic in the first place, but their outfits are almost never plain.
- Hollywood Costuming: The clothes aren't realistic, but have Artistic License as an excuse.
- Peacock Girl: For the instances someone just having a peacock tail.
- Gaussian Girl: People don't have a filter over them to hide skin blemishes.
- Gorgeous Garment Generation: So far, Real Life doesn't have things that make pretty clothes appear out of nowhere.
- Gorgeous Period Dress: Clothing in history is portrayed as almost all grand, no matter the situation or station of the people.
- Historical Beauty Update: People that objectively looked different than how they are portrayed in works.
- Impossibly Cool Clothes: Clothing that stands up to anything.
- Inhumanly Beautiful Race: That a species evolved to fit many human standards of beauty.
- Kicking Ass in All Her Finery: Even if the clothes don't get in the way of fighting, they still avoid damage and tearing.
- Progressively Prettier: An in-universe reason is almost never given for why some characters look more attractive over time.
- Wakeup Makeup: People don't wake up looking like they groomed themselves.
Works that make heavy use of this rule:
