Arrangement in Violet and Pink: Mrs Walter Sickert dates from between 1885 and 1887. 1
1885: The sitter's husband Walter Richard Sickert (1860-1942) commissioned a portrait of his wife, Ellen 'Nellie' Millicent Ashburner Cobden, Mrs W. R. Sickert (1848-1914). However, shortly afterwards he was in serious need of money and asked Whistler to let him have back the deposit:
'I want you if you can to let me have back the balance of £25 which you have on account for Nellie's portrait for a while. Of course whenever you can arrange to paint it & care to do so, we will make arrangements in good time to sell out & let you have the complete £100.' 2
1885-1886: Mrs Sickert sat to Whistler on 23 December 1885, and then there was a long delay (the Sickerts went abroad on 21 July 1886) but she suggested further sittings in December 1886. 3 It is, however, not entirely clear whether the sittings were for this portrait or for Green and Violet: Portrait of Mrs Walter Sickert y338.
1887: Arrangement in Violet and Pink: Mrs Walter Sickert was probably completed in October 1887, when Sickert sent Whistler a final cheque:
'I enclose a cheque for £42. 10. the balance for Nellie's portrait.
Of course it is impossible to thank you at all for doing us such a work. We shall always look upon it as practically a magnificent present. ... certainly the moneys are ludicrous, & bear no sort of proportion to the value of the work.
… Will you also tell your framemaker to send me in his bill for the frame.' 4
It was exhibited at the 64th Annual Exhibition, Royal Society of British Artists, London, 1887 (cat. no. 157) as 'Arrangement in violet and pink. (Portrait of Mrs. Walter Sickert)'.
Bernhard Sickert (1862-1932) stated in 1908 that, according to the sitter, the portrait was destroyed. 5

Arrangement in Violet and Pink: Mrs Walter Sickert, Whereabouts unknown

Green and Violet: Portrait of Mrs Walter Sickert, Fogg Art Museum
Only one title is known:
The punctuation was simplified for the 1980 catalogue, so 'Arrangement in Violet and Pink: Mrs Walter Sickert' is the preferred title.
The Artist described it as 'a full-length portrait of Mrs. Walter Sickert, an “Arrangement in Violet and Pink,” eminently powerful in handling, and full of refinement.' 8 The Sunday Times commented on the dress and décor: 'The dark violet dress ... against a pink curtain, and relieved by the red of a pretty hat and handkerchief is a masterly piece of painting. The right arm daintily holds the dress, while the left carries the hat.' 9 The Illustrated London News, however, described the dress as black silk, and the Standard said her hat was trimmed with red. 10

She also posed for the portrait reproduced above, Green and Violet: Portrait of Mrs Walter Sickert y338.
An art critic commented: 'The figure is beautifully drawn ... The dark violet dress ... against a pink curtain, and relieved by the red of a pretty hat and handkerchief is a masterly piece of painting' but added that the painting was 'barely completed.' 11
The portrait was probably destroyed.

The sitter's husband Walter Richard Sickert (1860-1942) commissioned a portrait of his wife, Ellen 'Nellie' Millicent Ashburner Cobden, Mrs W. R. Sickert (1848-1914). However, shortly afterwards he asked Whistler to let him have back the deposit temporarily. 12 In October 1887 Sickert sent Whistler a final cheque for '£42. 10. the balance for Nellie's portrait.' 13
According to The Sunday Times, the portrait was barely completed, and the paint had sunk in, when it was exhibited at the RBA, but it was described favourably:
'The figure is beautifully drawn, posed with grace and actuality, and is replete with refinement. The dark violet dress ... against a pink curtain, and relieved by the red of a pretty hat and handkerchief is a masterly piece of painting. The right arm daintily holds the dress, while the left carries the hat.' 14
Similarly, the colour harmony was appreciated by the Globe, but the reviewer criticized it for being 'undefined in form, and somewhat vaporous in effect'. 15
The Illustrated London News described Whistler's group of works: 'The central, and in a sense the most important, work is Mr. Whistler's “Arrangement in Violet and Pink” (157), but which to ordinary mortals is more intelligible as a portrait of Mrs. Walter Sickert.' 16 The Artist commended it as 'a full-length portrait of Mrs. Walter Sickert, an “Arrangement in Violet and Pink,” eminently powerful in handling, and full of refinement.' 17
