In 1996, the group were joined by sisters Nicole and Natalie Appleton and signed to London Records under their shortened name.

The group's influence on British fashion in the late 1990s has been noted, particularly their signature style of cargo pants in promotional imagery and live appearances.

In 1993, Blatt, Lewis and Simone Rainford were signed to ZTT Records, and Sugababes music manager Ron Tom decided the trio should become a group.

Some of the others names they considered included Slinky and Shifty, but ended up calling themselves All Saints 1.9.7.5. after the recording studio and the year of their births.

Natalie had to be persuaded to join the band, because she did not want to leave her daughter Rachel whilst she was overseas, but her parents stepped in and offered to look after their granddaughter for her.

[11] After forming a new group in May 1996, the four singers met with Karl "K-Gee" Gordon, a former band member of Outlaw Posse.

In November 1998, All Saints received the MTV Europe Music Award for Best Breakthrough Artist and performed at the ceremony, although Blatt was absent due to her pregnancy.

In February 2000, All Saints released the single "Pure Shores" as the soundtrack for the film The Beach, written by Shaznay Lewis and William Orbit, with the latter also producing the song.

[16] Also in 2000, the Appleton sisters and Blatt made their film debut with Honest, which was directed by former Eurythmics member Dave Stewart.

Honest is a black comedy set in Swinging London in the late 1960s, in which the singers playing three saucy streetwise sisters who head "up West" to pursue a life of crime.

Melanie Blatt said later that year that it was uncertain if they would reform, citing their difficulties with the financial and business aspects of the group.

[21] Studio 1 entered the albums chart at number forty, falling significantly short of the success of "Rock Steady" and the group's previous releases;[26] it received a Gold certification by the British Phonographic Industry (BPI).

[27] A second single, "Chick Fit", followed in February 2007, but promotional appearances and a physical release were cancelled and it failed to reach the top 200.

[28] It was subsequently reported that All Saints and Parlophone had parted ways and the group cancelled their planned UK tour.

We got signed before we had even made music again, it wasn't like we felt we had something to give back to the world... we were given an opportunity and took it, without really thinking about it too hard".

She also said she never felt comfortable with the success the band had and that "it was not necessarily the plan at the beginning; there was a lot of compromise involved".

The following month, in a press release for the Wideboys' single with Shaznay Lewis, titled "Daddy O", posted on the official website of All Around the World, it was stated that All Saints were recording in the studio and would be back with new material before the end of 2008.

On 25 May 2013, original All Saints member Simone Rainford died from kidney cancer a month after her 38th birthday in her home in Greenwich.

[32] In November 2013, it was announced that the group would be officially reforming for a second time to support the Backstreet Boys for five dates across the UK and Ireland in 2014.

[36] On 15 March 2016, the group announced their first headlining tour in 15 years in support of their 2016 comeback album, Red Flag.

[37] The Red Flag Tour would visit 10 British cities throughout October 2016, beginning in Newcastle upon Tyne and ending in Norwich.

[42] As with their previous albums, Karl "K-Gee" Gordon was involved in the production,[43] as well as William Orbit, who produced "Pure Shores" and "Black Coffee".

[44] On 29 May 2018, the group announced via their official Instagram account the name of their fifth album, Testament, along with its release date of 11 July 2018.

In February 2002, Blatt replaced Kelis's vocals on the UK release of the track "I'm Leavin'" by Outsidaz and Rah Digga; the single reached number 42.

In April 2005, Blatt returned to the music industry with a new single, "See Me", which was included on the Robots film soundtrack and peaked at number 78 in the UK.
