Emmelena (that sp) Sizer and Elizabeth Kirlin were among the society girls who performed as dancers at a 28 March 1915 benefit for the International Child Welfare League, at the Plaza in New York. Didn't see any of the other girls' names in the list, though. She also turns up in the list of girls dancing at a benefit for the New York Nursery and Child's Hospital, also at the Plaza in New York, in December 1915. With the two-m spelling, this seems to be the same woman: Emmalena Sizer Duncan (1894-1968), daughter of Mr. and Mrs. Robert Ryland Sizer of New York and Long Island; wife of David Duncan, WWI veteran, Harvard 1917. www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=12621868

Found something more specific:
These women are the fairies from an all-female amateur musical comedy (Old King Cole) put on for charity at the Plaza ballroom in New York on April 15, 1915 by Miss Spence's School Society. The Society was an alumnae group of The Spence School, a girl's school still functioning.(www.spenceschool.org) A New York Times account:

More photos from the production:

Marion P. Gibney Patterson was the daughter of Dr. and Mrs. Virgil Pendleton Gibney of New York City. In 1917 she married Dr. Daniel Cleveland Patterson (1882-1946) of Bridgeport. Daniel was a surgeon, founding member of the American Association for the Surgery of Trauma. Her father Virgil was also a surgeon, founding member of the American Orthopaedic Association, and first Professor of Orthopaedic Surgery at Columbia Medical College. A biographical sketch of her father: www.ncbi.nlm.nih.gov/pmc/articles/PMC2806971/

Sophie Young Hubbell was the daughter of Mrs. John Manning Young (formerly Sophia Milbank) of Lexington Avenue, at the time of her coming out tea, in December 1913. Marion Gibney attended the tea. Sophie married Captain George Loring Hubbell Jr., of Long Island, in October 1917. Her matron of honor at the wedding? Marion Gibney Patterson. The Hubbells had at least six children: George III, William (1929-2002), Elizabeth, Barbara (1924-2007), Sophie, and Susan. George Jr. was elected mayor of Garden City NY in 1931. www.arlingtoncemetery.net/wmhubbell.htm

This seems likely as the Eleanor Davies in the image: Eleanor van G. Davies was daughter of Mrs. Richard T. Davies of New York City, at the time of her debutante dance in January 1914. Eleanor married stock broker Eugene Hoyne de Bronkart (1888-1968) of Chicago, in January 1916. They had at least two children, a son, Richard Davies deBronkart (1922-2005), and a daughter Elinor. (Eleanor Davies seems to have used the spelling "Elinor" in adulthood.) www.capitalgazette.com/news/fortherecord/june-obituaries/... Her grandson Richard Davies "Dave" deBronkart Jr. (b. 1950) is notable as "e-Patient Dave," an advocate of participatory medicine, accurate health records, and patient empowerment: en.wikipedia.org/wiki/Dave_deBronkart

Apparently part of this larger image:

Hackstaff of 7 East 54th St., New York, NY www.mytrees.com/ancestry/Other/Born-1895/Ha/Hackstaff-fam... indicates that she was born in 1895 and her mother was Margaret Euphemia Hoffman
