[134][135] During its release week, Styles occupied the top spot of the album and singles charts in over fifteen countries, including the UK and US, with Harry's House and "As It Was," respectively.

[148][149] Steph Green, writing for the BBC, noted, "Harry Styles doesn't feel up to the material here, with leaden line delivery and a lack of light and shade making his scenes opposite Pugh fall flat,"[150] but some were more positive of his performance, with Owen Gleiberman writing, "With his popping eyes, floppy shock of hair, and saturnine suaveness, he recalls the young Frank Sinatra as an actor.

[153] Despite this, reviews for the film and his performance were less positive, with Robert Daniels of RogerEbert.com writing, "Here, Styles' inexperience as a leading man in a weepy British queer period piece is glaring.

[160] In July 2024, Styles joined Stevie Nicks on stage at the British Summer Time festival in Hyde Park in London to perform "Stop Draggin' My Heart Around" and "Landslide" in tribute of Christine McVie's birthday.

[177] He has also cited Freddie Mercury, Elvis Presley, and Paul McCartney (including his side project Wings) as influences, while mentioning Shania Twain as his main inspiration both musically and in fashion.

[206] In a 2015 Rolling Stone review of One Direction's concert at MetLife Stadium, Rob Sheffield said, "It's like watching the footage of Secretariat running the Belmont Stakes in 1973 — he's 31 lengths ahead of the other horses, but he speeds up madly for the final stretch because he's so in love with being fast.

[220][221] Ben Beaumont-Thomas of The Guardian wrote that he is "a star who has negotiated one of the most difficult transitions in music – from boyband to solo artist – with more panache than even successful forebears such as Justin Timberlake and Robbie Williams.

Artists such as SZA,[247] Miley Cyrus,[248] Elton John,[249] Shania Twain,[250] Olivia Rodrigo,[251] Chris Stapleton,[252] Mark Ronson,[253] Halsey,[254] Lorde,[255] Matty Healy,[256] and Troye Sivan have all voiced their wishes to collaborate with Styles.

[272][273] Nicole Saunders of Billboard noted that his fashion had "blossomed from a teen wearing purple Jack Wills hoodies to a carefully executed blend of '70s rock with a glamorous magpie feel" over the course of the group's five-year stint.

[274] Regarding Styles's time in One Direction, AllMusic writer Tim Sendra opined that his "charming persona and elastic vocals had him positioned as the Timberlake of the group.

[277] In 2016, he was featured in Another Man magazine,[278] after which Anne T. Donahue of The Guardian labelled him an "artthrob" who offers "something other than token shirtlessness" and telegraphs "an allegiance to the niche worlds of art and fashion rather than aiming for mainstream notoriety.

"[280] As a solo artist, Styles has opted for "candyfloss" custom pink suits, sequined tops, printed satin flares and a Gucci-heavy aesthetic.

[44][297][298][198][299][300] He has been credited with increasing sales and attention for smaller brands such as Bode, Éliou, Egonlab, S.S. Daley, Daniel W. Fletcher, Marco Ribeiro and Arturo Obegero.

[305] The V&A Museum acquired the cardigan for its permanent collection in November 2020, calling the viral craze a "cultural phenomenon that speaks to the power of creativity and social media in bringing people together in times of extreme adversity.

[317] Unveiled at Milan Fashion Week, the collection included tailored wool and velvet suits, tweed trench coats, tartan kilts, bowling shirts, and printed pyjamas.

He has been attributed to the popularization of items such as pearl necklaces, Hawaiian shirts, crochet garments, chelsea boots, feather boas, and wide leg trousers.

"[44] In 2013, Styles and fellow One Direction member Liam Payne became ambassadors for the cancer charity Trekstock, raising over US$800,000 through the online fundraising platform Prizeo.

"[357] In 2014, Styles joined LGBT rights charity Stonewall's #FirstSnog campaign in celebration of their 25th anniversary[358] and showed support for Michael Sam, the first openly gay player drafted by an NFL team, by wearing his jersey onstage during One Direction's concert in St.

"[394] On 2 June 2022, Styles announced he was donating his appearance fee from Apple's AirPods' spatial audio campaign to the International Rescue Committee, a global humanitarian aid organization that is responding to the more than six million refugees being forced to flee Ukraine.

[401] Styles donates items to the organization's annual charity relief auction, including multiple autographed Gibson and Gretsch electric guitars, and signed versions of his albums.

The initiative gave Styles the idea to write a song titled after the slogan, which serves as the penultimate track on his second studio album, Fine Line.

and the acronym "TPWK" were spotted in London, Tokyo, Los Angeles, New York, and Australia; fans were able to connect the posters to Styles and his new album release because of the reference to his "Treat People with Kindness" motto.
