''Mr Selfridge'' is a TV series about the American Harry Selfridge (Jeremy Piven), who moves to London in 1909 with the intention of building a magnificent new department store. Drama ensues as he tries to make his store successful in spite of conservative British customs, his opportunist financier Lady Mae (Katherine Kelly), his own marital troubles with his wife Rose (Frances O'Connor), and, in season 2, the impending World War One.

Meanwhile, shopgirl Agnes Towler (Aisling Loftus) has her own personal troubles to deal with, including her rebellious brother George (Calum Callaghan), her rivalry with catty shopgirl Kitty (Amy Beth Hayes), and her burgeoning romance with Henri [=LeClair=] (Grégory Fitoussi); and Josie Mardle (Amanda Abbington) tries to stay strong in the face of her secret love affair with Mr Grove (Tom Goodman-Hill).

!!This series has examples of the following:
* AlphaBitch: Kitty certainly behaves like one, especially towards Agnes in early season 1.
* AristocratsAreEvil: Lady Loxley has shades in this in season 1, obviously having ulterior motives whenever she helps Harry out. However, she pales in comparison to her husband, who, as revealed in season 2, abuses her physically and emotionally, believes in MaritalRapeLicense and has highly shady business deals going on.
* AwfulWeddedLife: Lord and Lady Loxley: in season 2, Lord Loxley moves in with her, and it's shown that she ''really'' had reason to like things the way they were in season 1.
--> '''Lady Mae''': When Lord Loxley is in London, I'm in the country, and when Lord Loxley is in the country, I'm in London. That's the secret of a happy marriage.
* DarkerAndEdgier: Season 2 in comparison to Season 1, mostly because of WWI: the first season ran on plots of shopgirls fighting over promotions, getting celebrities to visit Selfridge's, and love affairs. The second one runs on plots of young men enlisting, characters trying to find ways to help the war effort, espionage, [[ArsonMurderAndJaywalking and love affairs]].
* DeliberateValuesDissonance: So, so much. Woman employees are fired if they decide to marry (and note that Harry is supposed to be a fairly progressive employer); Harry's wife Rose shrugs on his sleeping with other women but woe on Rose if she even kisses another man; the Empire Exhibition treats the British Empire as a fantastic thing with no consideration for the negative sides of colonization, and so on...
* DomesticAbuse: Lord Loxley to Lady Mae.
* DoubleStandard: See DeliberateValuesDissonance for one example.
%%* DrivenToSuicide: [[spoiler: Miss Bunting]], poor thing.
* EveryoneLooksSexierIfFrench: Oh, Henri. Is there a woman you haven't charmed?
* GoldDigger: Lady Mae; it's implied she married Lord Loxley purely for the money and title.
* GorgeousPeriodDress: One of the most-praised aspects of the programme.
* GRatedDrug: Ellen Love's implied cocaine use: and by implied we mean that she does it on-screen, and it is fairly obvious that it's supposed to be cocaine although the drug isn't named. Other characters treat it as a vice little worse than smoking. TruthInTelevision, again, as cocaine was legal at the time, and it was a fairly acceptable vice as long as the user remained a FunctionalAddict.
* HistoricalDomainCharacter: Ernest Shackleford, ArthurConanDoyle, Anna Pavlova, all of whom made RealLife appearances at Selfridges. In Season Two, [[SilentMovie producer Mack Sennett and actress Mabel Normand]] appear (although ''not'' in RealLife).
* HomeByChristmas: what ''almost'' every one keeps saying will happen when [[spoiler: the male Selfridges employees go off to fight in WorldWarOne.]]
* ImpoverishedPatrician: Lord Loxley. His attempts to make money are major plot points in season 2.
* IWantMyBelovedToBeHappy: [[spoiler:Victor]] releases [[spoiler:Agnes]] from their engagement because he knows she loves [[spoiler:Henri]] more than she could ever love him.
* MaritalRapeLicense: As far as Loxley's concerned, Mae has no right to say no.
* MayDecemberRomance: The past-childbearing-age [[spoiler:Josie Mardle]] with [[spoiler:her much younger Belgian boarder, Florian Dupont]]. She thinks it could never work because of this; he doesn't give a damn and wants her anyway.
* MissKitty: Delphine Dey, author and owner of a high class drinking establishment, in Season Two. She becomes [[spoiler: friends with Rose Selfridge.]]
* NoNameGiven: Mr Thackeray, Mr Crabbe and Lord Loxley.
* PornStash: Gordon acquires a small one in 2.03. (By today's standards, it wouldn't be considered porn at all: the pictures are of women wearing knee-length dresses, sitting on beds, but the characters treat them as "racy". TruthInTelevision, as in the 1910s a respectable woman would ''never'' wear clothing that revealed even her ankles in public - [[FullyClothedNudity a knee-length skirt]] was practically nudity.)
* ShedTheFamilyName: A variation: Lady Loxley insists on being addressed as Lady Mae[[note]]despite this being technically incorrect; see TheBritishTitleSystem[[/note]]. Probably because her husband Lord Loxley is a total jerk and {{domestic abuser}}.
* ShutUpKiss: [[spoiler:Florian]] gives one to [[spoiler:Miss Mardle]] as she's trying to list all the reasons a relationship between them would never work. She promptly goes up like a bundle of tinder in his arms before forcing herself to stop.
* StepfordSmiler: Harry is the most cheerful, bombastic, larger-than-life person these characters will ever meet. But when he's by himself he shows strong signs of being severely depressed, even alluding to suicidal urges in the first episode.
* SugarAndIcePersonality: Josie Mardle. Tries to be cool and controlled; is actually secretly {{adorkable}} and sweet.
* WorldWarOne: breaks out in Season Two.
* YourCheatingHeart: Harry. Rose. Lady Mae. Mr Grove. Just about everyone.
