->''"The party is '90s-themed, so we're dressing the way we did back then, AKA hella fresh."''
-->-- '''Jake Peralta''', ''Series/BrooklynNineNine'', "The Tattler"

A common staple in fiction and in RealLife. There are always parties which are centered around certain decades which remain firmly in the minds of people (who may or may have not lived such decades) and popular culture. Such parties are usually based around music, fashion, dance styles and/or movies of a decade. The most popular ones tend to be TheRoaringTwenties, TheFifties and TheEighties. TheSixties and TheSeventies are also popular choices, primarily during TheNineties and TheOughties respectively, with these decades being irony fodder.

This celebration of the past might come from the use of a NostalgiaFilter. As people grow older, they start to miss their youthful days, where things seemed a lot simpler and, well, fun. Hence why these parties are usually organized. Nostalgia is connected to the need of escapism and the need of reminding what you've left behind, from things like clothes to old friends. However, people also tend to celebrate decades they barely or even haven't lived through just because the fashion seems more appealing or glamorous.

!!Examples:

[[folder:Comic Books ]]
* The cover of one ''[[ComicBook/ArchieComics Archie's Double Digest]]'' from the 2000s had the gang at a "retro party". Based on the clothes Betty and Veronica turned up in, we assume the party's organizers had TheSeventies in mind, but Archie shows up in a caveman costume, calling it "the ultimate retro look."
* ''ComicBook/TheFabulousFurryFreakBrothers'': A comic from the 1970s had the guys throwing a '50s-themed New Years party. Franklin is a holdout, [[NostalgiaAintLikeItUsedToBe declaring the decade "a drag"]], and as the story recalls their ''real'' '50s party some 15 years earlier, with its reckless drunkenness, sexual frustration, and violent, destructive juvenile delinquents, they decide to have a naked sex-and-drugs '60s-themed party instead.
[[/folder]]

[[folder:Comic Strips]]
* The main characters in ''ComicStrip/{{Doonesbury}}'' started holding TheSixties revival parties in the mid [[TheSeventies 70's]], when they were very recent history. In the same strip, the characters would parody this trope by having an end-of-decade party, coming as iconic moments from the decade that had just passed.
[[/folder]]

[[folder:Film -- Live-Action]]
* From the 2002 Australian comedy ''Film/{{Crackerjack}}'' about the elderly members of a lawn bowls club.
-->"How about we have a fancy dress party, and we all come dressed like our favourite decade?"\\
"We tried that before, and [[TheFabulousFifties everyone dressed like the Fifties]]."
* ''Film/TheLocals'': Because of the way they are dressed, Grant and Paul assume that Kelly and Lisa are on their way to 80s themed party and accept their invitation to follow them. [[spoiler:They later learn that the girls had died on their way to a party in the 80s, and are [[JacobMarleyApparel still wearing the clothes they were in when they died]]]].
* ''Film/NeverBeenKissed'': Discussed. The kids wants to have a "Millennium" themed prom but it turns out another high school does that as well and they want to be unique. Their teacher suggests an '80s prom but they boo to that idea. (They choose "famous couples throughout history" after all.)
[[/folder]]

[[folder:Literature]]
* In ''Literature/ABoyMadeOfBlocks'', Isobel invites Alex to a party based on TheSixties. Alex wears a suit that makes him feel like Film/AustinPowers.
* {{Exaggerated|Trope}} In John Brunner's ''Literature/StandOnZanzibar'', since this is updated to a "Twentieth Century Party". The confusion about whether 2000 C.E. counted as Twentieth Century or Twenty-First was referenced, one of the few predictions the book got right.
[[/folder]]

[[folder:Live-Action TV]]
* In an early episode of ''Series/TwoBrokeGirls'' the girls are kicked out of a late night laundromat because the laundromat is the location for an 80s themed rave/party with special guest VIKI from ''Series/SmallWonder''. Max is unironically pissed at being too poor to attend. She loved ''Small Wonder''.
* ''Series/BrooklynNineNine'', "[[Recap/BrooklynNineNineS6E03TheTattler The Tattler]]": Jake and Gina go to their 20-year ClassReunion with a dress code and a theme from their high school days. Jake and Gina revisit their DDC style, which means the Dope Denim Crew. They have baggy denim hoodies. Jake's wife Amy wears a cute floral dress, a pair of Doc Marten’s, a black choker and a small backpack. Jake's friend from their ska band is implied to wear '90s outfits all the time.
-->'''Jake:''' Our 20-year high school reunion is tonight, and the party is '90s-themed, so we're dressing the way we did back then, AKA ''hella'' fresh.
* The ''Series/{{Charmed|1998}}'' episode "Muse to My Ears" has a minor subplot of a party being thrown at P3, and Piper getting annoyed that the client wants a theme. Paige suggests a 1940s theme, and the climax of the episode takes place at the party. TheStinger has Phoebe and Cole dressing up and dancing to period appropriate music.
* In the ''Series/FamilyTies'' episode "I Know Jennifer's Boyfriend," Jennifer has a 1950s-themed birthday party, with posters of Creator/JamesDean and an authentic '50s jukebox playing rock and roll.
* ''Series/GilmoreGirls'': Played for laughs. Rory attends a 2002-themed party which Olivia throws for her friend Lucy's birthday. The episode is set (and aired first) in 2007.
* There's an episode centred around an 80's party in ''Series/{{Hellcats}}''.
* An episode of ''Series/{{House}}'' features an "80's Party". Dr. House comes dressed in late 18th/early 19th century garb because the invitation just said 80's, and didn't specify a century. Doubles as an ActorAllusion due to his role as the Prince Regent in ''Series/{{Blackadder}}''.
* In ''Series/KathAndKim'', Kath arrives in her everyday's clothes (which she hasn't changed since TheEighties) to an 80's themed party.
* ''Series/LizzieMcGuire'' has an episode where Gordo adopts an aesthetic inspired by 60s lounge music. It catches on with the entire school, and they throw a dance with a 60s theme.
* ''Series/MidsomerMurders'': In "[[Recap/MidsomerMurdersS10E1 Dance with the Dead]]", the village of Morton Fendle is obsessed with the now disused WWII airfield based there. They hold a 1940s themed dance that the Barnabys and Jones attend.
* An episode of ''Series/PerfectStrangers'' had Larry and Balki throw a 50's themed party where one of the guests was a hypnotist. He tried to hypnotize Larry into thinking he was Elvis, [[HypnoFool but wound up hypnotizing Balki instead.]]
* The ''Series/RedDwarf'' episode "Balance of Power" has a flashback showing the characters at a party with a sign on the wall saying "Nostalgia Night 1990s". (The scene is set in the 21st or 24th century, depending on the {{Retcon}}s.) The so-called '90s themed party looks like a cross between TheSeventies (for example, the disco ball) and TheEighties (for example, the extravagant, campy clothes). Such cues and many more were taken from said decades because the episode itself was made in 1988.
* ''Series/SavedByTheBell'' episode "Slater's Sister" had the students attending a sock hop party set in, where else, but the 50s. This was just the subplot though; as the episode name states, it had Slater's returning [[RememberTheNewGuy (and never before mentioned)]] younger sister J.B. begin to date Zack, to her brother's chagrin.
* ''Series/ThatsSoRaven'' has Raven discovering that the Chill Grill was previously a jazz club in the 1940s, and meets a woman who was once a famous singer. So she and friends throw a 1940s themed night and invite the woman to perform again.
* Several episodes of ''Series/TheVampireDiaries'' have featured the main characters attending high school dances themed after certain decades (called Decade Dances in-universe).
[[/folder]]

[[folder:Music]]
* Music/TheSaturdays' video for "Disco Love" has the group cycling through three decades. First is an outdoor gathering in the 70s, second is a roller disco in the 80s and finally a rave in the 90s.
[[/folder]]

[[folder:Video Games]]
* The second UsefulNotes/NintendoDS ''VideoGame/GuitarHero'' title is set in a rock festival made of several of these, ranging from the 2000s to TheSeventies. However, the 2000s are split into "modern" and "2000".
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/TheWotch'' had a 1970's themed dance (which annoyed Mingmei because she hadn't enjoyed the decade the first time around).
[[/folder]]

[[folder:Web Videos]]
* ''Website/CollegeHumor'', "Realistic 80s Costume Party": Janie and Raph attend an 80s dress up party. Janie is excited because she loves popped collars, big 80s hair, dancing to music heavily relying on synthetizer and wearing leggings, but it turns out others find her generic costume offensive because literally millions of girls lived in the 80s.
[[/folder]]

[[folder:Western Animation]]
* The pilot for ''WesternAnimation/AllGrownUp'' features the parents attending a 70s themed party, and competing in a disco dance contest.
* In ''WesternAnimation/{{Daria}}'''s episode "Life in the Past Lane", Jane is dating Nathan who is obsessed with swing dancing and the styles and manners of TheForties. They go to a dance party and to a drive-by cinema meeting centered around said decade.
* ''WesternAnimation/KingOfTheHill'': In "Strangeness on a Train", Peggy plans her birthday party on a train: a murder mystery theatre train ride combined with 70's disco theme. Hank is not sure it's such a great idea, especially the disco part, but agrees with it to make Peggy happy. Their friends show up in their disco outfits, as well as most of the actors (but those have also costumes for their roles in the play). Many things go wrong with Peggy's party. The episode ends with a small impromptu disco-themed party at a random bar. The bartender hangs up a disco ball and finds an appropriate soundtrack. Peggy's friends dance in their disco outfits.
* ''WesternAnimation/TheSimpsons'':
** Marge's OldFlame Artie Ziff tries to woo her back by recreating their prom and paying everyone in town to dress like they did in TheSeventies. (Disco Stu, of course, "is working pro bono.")
** One episode has ''Greaser's Cafe'', which is built around this trope (concerning TheFifties, to be specific.) The owner boasts that in there, the fifties will never go away. [[TemptingFate Soon thereafter, the cafe has to close down.]]
[[/folder]]

[[folder:Real Life]]

* Just google the words of the title. There'll be hundreds of matches for all kinds of decade parties, especially from TheEighties, which is likely to be the one easiest to represent visually. For some reason or another, these tend to be about the pop culture of 30 years earlier.
* Buffalo, New York's [[https://www.theworldslargestdisco.com "World's Largest Disco,"]] an annual seventies themed party that revolves around thousands of people dressing up in fashions from 1970s and turning a major metropolitan convention centre into ''one gigantic convention hall sized disco.''
