A young couple are all ready for the [[WeddingDay big day]]. Only the bride isn't who the groom thinks she is. Maybe it's an ArrangedMarriage, and someone else is impersonating the bride he's never seen. Maybe a [[VoluntaryShapeshifting shapeshifting alien]] has taken her place. Or maybe she's simply using a wedding veil as a convenient disguise.

The wedding rarely if ever goes through, with the real bride (or groom, in gender-flipped examples) [[SpeakNowOrForeverHoldYourPeace bursting in at the last moment]]. Very occasionally, the groom may fall in love with the "fake" bride and marry her for real. Legal trickery may establish that the false bride can be treated as the true bride's proxy, and so he really did marry the true bride. In many FairyTales, the false bride is executed for her attack on the true bride -- sometimes substantially after the wedding took place -- as a complication in the heroine's RagsToRoyalty rise. (This is often a case of SiblingTriangle.)

Note that many of these rules are reversed if it's [[AndNowYouMustMarryMe a villain who's trying to marry our plucky heroine]] for devious and evil reasons. In these cases, the villain often does end up married to the fake bride, usually for the sake of invoking some comedic comeuppance.

Compare BedTrick, which is the less G-Rated version of this trope.

[[folder:ComicBooks]]
* ''{{Sub-Mariner}}'' #36 (1970s): Llyra tricks the Sub-Mariner into marrying her instead of Dorma, who's been kidnapped. It turns out that Atlantean marriage laws let you use a substitute at your wedding—he is considered to have married Dorma anyway. The official had put Dorma's name down on the wedding document, which is what made Llyra just a stand-in.
* In ''ComicBook/FantasticFour'' #300, Johnny Storm marries Alicia Masters, but a later {{retcon}} made the Alicia he married really a Skrull shapeshifter.
* TheFlash #165 (1966), "One Bridegroom Too Many": At his wedding to Iris West, Barry Allen is replaced at the altar by his EvilCounterpart, Professor Zoom, who uses future technology to disguise himself as Barry. Luckily, Barry is able to stop the wedding in time and defeat Zoom.
* A ''ComicBook/{{Diabolik}}'' has a rather unusual example involving the title character: as part of his current plan, Diabolik has disguised himself as Ginko, who is invited to a wedding, and when the wedding gets bombed Ginko's fiancee Altea, who has been wounded, has 'Ginko' marry her. The story ends with Diabolik explaining his lover Eva that [[StatusQuoIsGod neither him nor Ginko are legally married to Altea, as Benglait's laws don't allow for a stand-in and he was there under a false identity]], with a later story making things even stranger by revealing that [[spoiler: Altea's late husband actually [[FakingTheDead faked his own death]] to prevent being discovered as a terrorist leader ([[StatusQuoIsGod Diabolik kills him for real by the end of the story]])]].

* ''TheSwanPrincess'' has Derek proclaim a vow of everlasting love to Odette, because those are the terms that will break Odette's [[BalefulPolymorph swan curse]].

[[folder:{{Literature}}]]
* In ''Book of a Thousand Days'' by ShannonHale, Lady Saren forces her maid, Dashti, to [[PlayingCyrano act as her when interacting with her fiancé]], Khan Tegus.

* [[http://gracelivingstonhill.com Grace Livingstone Hill]] must have loved this trope, because she used it in two separate novels: ''Exit Betty'' (Betty is nearly tricked into marrying the cousin she hates instead of the one she tolerates) and ''Dawn of the Morning'' (where the substitute husband is far better than the original).
* Towards the end of Creator/SheriSTepper's ''The Companions'', main character Jewel does this to her ex-husband, who is still infatuated with her. She has the identity of the fake bride concealed by telling him that veiling the bride until the wedding night is a tradition of the planet she now lives on. On the wedding night itself, she uses [[AppliedPhlebotinum scent-language shenanigans]] to de-infatuate him with herself and re-infatuate him with his new bride. He doesn't mind, but his mother is not amused. That is to say, she opens fire.

Unfortunately, Jamie was three sheets to the wind and thought she was Rose, which Leona doesn't realize until after it's too late. Later, but before Rose arrives home, Logan goes to the Church Council and convinces them that Jamie had changed his mind about which sister he wanted to marry and was simply too impatient to wait for new wedding banns, persuading them to declare him legally married to Leona rather than Rose.
* In ''Literature/OnFairyStories'', Creator/JRRTolkien discusses the use of this in terms of ''Literature/TheGooseGirl'' and Bertha the mother of Charlemagne -- and points out that without evidence to the contrary or fantastic elements, you can't disprove it of Bertha by showing it's a widespread story.
* MarcusDidiusFalco pulls this to stop a forced marriage involving his LoveInterest Helena Justina. The villain says he can just get the marriage annulled, whereupon Marcus grins and points out that he won't live long enough to do so (as he's bleeding from a fatal wound and Marcus is preventing him from getting help).
* TheRedTent has a variation - Leah stands in for her sister Rachel on her wedding day because Rachel is young and afraid of the whole sex-and-babies obligation. The groom is well aware of the switch, but pretends not to be because he is equally attracted to Leah.

[[folder: LiveActionTV]]
* One of the '''many''' [[GambitPileup Gambit Pileups]] in ''Series/AlloAllo'' had Rene due to marry the leader of the Communist resistance, who was replaced by his waitress Yvette, who was then replaced by his wife Edith (although Rene at that point was playing his own twin brother). The vicar had also been secretly replaced by Officer Crabtree, so we aren't sure exactly whether ''anyone'' had managed to get married.
* One time on ''TheAndyGriffithShow'', [[FullNameBasis Ernest T. Bass]] tried to steal a bride away from her wedding but it turned out to be Barney Fife under the veil.
-->'''Ernest T:''' I'm a little mean, but I make up for it by bein' real healthy. Say you'll be mine. Say you'll be my beloved!
-->'''Barney:''' ''(lifts veil)'' I wouldn't marry you if you were the last man on earth!
* In ''Series/PowerRangersRPM'', the good guys do this, the bride to be [[spoiler:Summer, the Yellow Ranger]] is replaced by [[spoiler:Dr. K]] after the bride realises that not only does she really not want to go through with her ArrangedMarriage but that she needs a diversion because the enemy has infiltrated the wedding.
** This happens again in ''Series/PowerRangersSamurai'', when Mia and [[spoiler:Emily]] pull a BatmanGambit on Dayu, who has been kidnapping brides from their weddings.
* On ''Series/{{Charmed}},'' Paige's old friend/on-and-off boyfriend is getting married, and having been turned insane by some sort of magic (as usual), she winds up trying to get rid of the bride and turns herself into a copy. Thankfully Leo rescues the real bride and sets everything straight just in time.
* There was a LifetimeMovieOfTheWeek called ''What Matters Most''. At the end of the movie, there is a wedding. The viewers are led to believe that the boy is going to marry an AlphaBitch, per his father's wishes. However, when the bride arrives at the altar, she is revealed to be his HighSchoolSweetheart who is also the mother of his child. The couple marries after the boy's father reluctanly gives his blessing to the young family. Just before the credits roll, his best friend narrates in a voice-over that the AlphaBitch and her GirlPosse along with the boy's mother arranged the whole thing.
* On ''The A-Team'', the team is hired to get the bride out of the shotgun wedding she's being forced into. To get the bride out, they put Murdock in her wedding dress. During the ceremony, when asked, "Do you take this man ...", he pulls back the veil and says, "I didn't go through all this just to see how I'd look in white!"
* Happens in ''{{Spellbinder}}'', when [[DarkActionGirl Ashka]] is convinced (with some difficulty) to take the place of the princess whom the barbarian leader is forcing to marry him in order to legitimize his takeover of TheEmpire. Just as the bride is expected to say "I do", Ashka lifts the veil and tells the shocked barbarian that she'd rather marry a pig.

[[folder:Religion and Mythology]]
* Literature/TheBible gives us the story of Jacob, who labored for seven years without pay for the right to marry the woman he loved, Rachel. The next morning he discovered that his bride was Rachel's older sister Leah, and that the deception was orchestrated by their father Laban because he thought it was improper for the younger daughter to be married before the elder. He did get to marry Rachel too the next week, but then he had to work ''another'' seven years for her retroactively.
** This, incidentally, is supposed to be the origin of the whole "lifting the veil" tradition. (Presumably Leah's wasn't see-through.)
** The retelling of this story in ''TheRedTent'' suggests that this was a deliberate Bride and Switch on the part of the two daughters.
*** Literature/TheTalmud, IIRC, says that Rachel suspected Laban might try this and arranged for her and Jacob to give each other subtle cues at the altar so he would know whom he was really marrying. However, right before the wedding Rachel realized that Leah would be humiliated if Jacob called the wedding off and revealed the signs to her.
*** At least one straight-to-video live-action series drew heavily from both sources in portraying the patriarchs; for this story, it had Leah imitating a certain tongue-clicking noise Rachel and Jacob had regularly used as a means of sounding each other out in the dark.
* In NorseMythology, the giant Thrymr steals Mjollnir in order to demand Freya as his bride; after Freya refuses, Loki comes up with the cunning plan to dress Thor in women's clothing and a veil. It works, albeit with some fast talking from Loki as Bridesmaid. The giants hand the "bride" Mjollnir, and Thor throws off his veil and kills them all.

[[folder:{{Theater}}]]
* ''The Ugly Duckling'' by A.A. Milne (not to be confused with the fairy tale by Creator/HansChristianAndersen) has a double version of this. The beautiful lady-in-waiting is recruited to woo the visiting prince, but the intended bride, the plain princess, will be married in heavy veils. Meanwhile, the prince plots the same thing with his dashing footman and a suit of ceremonial armor. [[PerfectlyArrangedMarriage Fortunately]], the prince and princess meet on their own and fall in love.
* Inverted in ''MuchAdoAboutNothing''. Claudio has been led to believe that Hero has died of grief over his accusations of sluttery, and to atone he has promised to marry her cousin sight unseen. But it turns out that it really is Hero.

* Done in [[MultipleEndings three of the four prologues]] of ''VideoGame/{{Aveyond}}: The Lost Orb'', where Lydia magically disguises herself as the girl Edward intends to marry. Unfortunately for him and his real bride, Mel reveals the deception too late, and the marriage is considered legally binding.
* Near the end of ''VideoGame/TheSecretOfMonkeyIsland'', [[BigBad LeChuck]] is about to marry governor Elaine Marley when pirate-wannabe Guybrush Threepwood burst into church to stop the wedding. Unbeknowst to both villain and hero, Elaine escaped much earlier and [[TotemPoleTrench the bride is actually two monkeys in a dress]] armed with a ghost-destroying seltzer bottle, ready to strike at the right moment. Guybrush naturally [[NiceJobBreakingItHero manages to mess that up]].
* In ''[[{{VideoGame/Sly3HonorAmongThieves}} Sly 3: Honor Among Thieves]]'', [[{{HeroAntagonist}} Carmelita Fox]] switches herself with Jing King when [[spoiler: she is [[{{BatmanGambit}} tricked]] into thinking Sly is planning to take General Tsao's place and marry her.
