Don Loper was an American fashion designer, screenwriter, choreographer, producer, actor, and assistant to MGM musicals producer Arthur Freed. He began his career as a dancer and was teamed with Ginger Rogers in Lady in the Dark. Loper was possibly the first openly gay man to ever appear on TV as himself, and not pretend to be straight.
While in the dress shop, Ethel says "Jane Sebastian will be absolutely green." Jane Sebastian was a very good friend of Vivian Vance. Ms. Vance was the godmother of her son, musician John Sebastian.
Don Loper tells Lucy that she can't wear her dress in the fashion show because Mrs. Alan Ladd decided to wear the same dress; however, Mrs. Ladd doesn't appear in the show.
The background music played during the fashion show is George and Ira Gershwin's song "Embraceable You" written for their musical Girl Crazy.
Bennett Green appeared in many Lucy episodes, sometimes with speaking roles, more often sitting or standing in the background when extras were needed to fill a scene. In the fashion show sequence at the end of this story, he appears in two different places at the same time: he is in front at the right of the walkway where the clothes are modeled, and he is also seen sitting with a woman behind Ethel at the back of the room.
