Dorrie exhibited at the Walker’s Gallery, London from 1935 - 1939. Copies of the catalogues are held in the National Art Library, V&A.

ART BY FOUR WOMEN
The Queen found time to pay an unexpected visit to an exhibition of works by four women artists even before it was officially opened. It was encouraging to the artists.
As a fact, the Walker Galleries, London, are well supplied with women’s exhibitions at the moment. The student of art will find there a very interesting collection, especially from the women’s point of view.
There is not only an exhibition of four women’s work, all in one gallery, but in an adjoining gallery are flower portraits, as well as studies of native life.
Perhaps to a modern woman, of the four women’s work, the hand-wrought jewellery by Dorrie Nossiter will have the greatest appeal. She has designed rings, necklaces, clips, and ear-rings__ear-rings being perhaps the most handsome of all, for, as Miss Nossiter believes ear-rings are always “in.” And she gives her works of art such charming appellations as “Quiet evening,” “Stamboul,” and “Treasure Trove.” (Anon 1935)

Dorrie's 1935 exhibition was described as follows in the Times, and advertised in the Times May 27th, 1935 (Anon 1935a). 

". . . and Miss Dorrie Nossiter hand-wrought jewellery. This last combines a delicate fantasy in the settings with good taste in colour in the choice of stones, a slightly exotic flavour being an advantage. An ear-shaped jewel, to cover the whole ear, must be a novelty." (Anon 1935b)

The card below was given out by Dorrie this one isn't complete but shows also that Dorrie's Jewellery was advertised as being "By appointment to the late King George V" on the opposite side can see a "To" for additional appointments to royalty but as yet not sure to whom this applied.
