[3] The tour was temporarily halted on May 22, 2017, due to a terrorist bombing that occurred shortly after the Manchester Arena show, killing 22 concert-goers (excluding the perpetrator) and injuring 1,017 others.

On November 29, 2018, Grande released a four-part docu-series on YouTube titled Dangerous Woman Diaries that included behind-the-scenes footage from the tour, performances as well as the creation of her fourth studio album, Sweetener (2018).

On May 23, 2016, Ariana Grande announced on social media that she would go on tour starting in late 2016 or early 2017 and that fans who ordered her album before May 25 would get a code to purchase tickets before the general public sale.

Describing the concept of the outfits used during the shows, Hearns stated: "It's about making an adult Ariana, marrying her silhouette with what's happening in fashion right now, so a big theme is sportswear—everything is oversized, there are straps everywhere, and cool hardware ...

The fourth part of the show started with Grande returning to the catwalk area of the stage wearing a bra and a pair of denim harem pants with black high heel shoes (a brown jumpsuit dress with a moon on it wearing white high heel shoes during the Europe leg onwards) and singing "Moonlight" as she sat and knelt on the edge of the catwalk in front of a celestial background with celestial projections.

[16] There ensued an optional interchangeable section of the concert, which featured anything from Ariana singing the original version of "Honeymoon Avenue", to Ariana singing a cover of Pink + White by Frank Ocean (this was changed to Grande performing "Somewhere Over The Rainbow" after performing "Thinking Bout You" starting with the show in Paris after the Manchester Arena Bombing).

[15] For the encore, after a two-minute silence, Grande performed "Dangerous Woman", wearing a black latex dress, with red lighting and pyrotechnics on the stage.

For example, in a review for Las Vegas Weekly, Ian Caramanzana wrote: "Grande's burly, soulful vibrato and wide range remain the star of her show, and she's at her best when it's just her, a microphone and her band – especially when she performs ballads".

[14] Ed Masley commented for The Arizona Republic that Grande has grown "into a self-assured R&B diva with the vocal chops to back up the confident swagger she brought to the stage.

[16] Billboard's Kristin Corpuz said of Grande's performance at Madison Square Garden: "She's showing off a more mature sound and edgier image.

With outfits custom-made by celebrity fashion designer Bryan Hearns, Grande electrified the Madison Square Garden stage with her four-piece rhythm section and 10 backup dancers.

"[17] A Billboard report later commented of the last concert of the tour that Grande "more than delivered with her impressive vocal range, sultry dance moves, unstoppable energy and a whirl of costume changes.

"[18] In a more mixed review, Chris Kelly of The Washington Post thought that "her gorgeous four-octave soprano was often obscured by her bass-heavy backing band", but he described the show as "a pristine showcase of her immense vocal talent.

"[19] Dan Hyman of Chicago Tribune opined, "[A]side from a massive projection screen that lived behind the stage and stretched the width of the arena, the production seemed a bit cheap for a show of this scale.

But it doesn't matter for this gifted singer: all Grande needs do to ... is dial back the bass and belt out some of her magnificent vocal runs.

On May 22, 2017, after Grande's show at Manchester Arena in England finished, a shrapnel bomb explosion caused the death of 22 concert-goers and 1,017 injuries.

Grande also re-issued "One Last Time" in addition to a live cover of "Somewhere Over the Rainbow" as charity singles, with all proceeds going to the British Red Cross.

[23] Alfredo Flores, Grande's tour photographer, told Refinery 29 that, after the bombing: Ariana was nervous, of course, but she was also excited to get back on the road, and so were we.
