(A list of suggestions for costumes for sisters that also work for any pair or group of women. I can just imagine my sister’s reaction had I ever suggested dressing her as a slave to my Circassian Princess…)
SISTERS who desire to appear in costumes which assimilate might choose any of the following: Apple and Pear Blossoms, Sovereign and Shilling, Cinderella’s two sisters, Cordelia’s sisters, Brenda and Minna Troil, Brunhilda and Kriemhilda, Salt and Fresh Water, the Roses of York and Lancaster, a Circassian Princess and Slave, Music and Painting, the Two Nornas, Lovebirds, Aurora and the Hours, Oranges and Lemons, and Four Sisters as the Seasons.
