From 8-year old Hilda’s diary:

Last night Aunt Tillie put on her most beautiful evening gown. It is yellow satin and has a very low neck, so low that the bumps in her front show almost half naked and it has a long train that she picks up by holding a loop when she goes downstairs. She has yellow slipper and diamond pins in her hair and she smelled like all kinds of flowers mixed together. She told me that Suzanne and two gentlemen were coming to our house for dinner and that afterwards, they were all going to the theater together. I asked if I might come to the table but Aunt Tillie said that I couldn’t, as children don’t eat with grown-ups. I wanted to ask her why I have to eat with Tante Esther and Uncle Felix and all the other people I don’t like. I didn’t, as I remembered that Aunt Tillie doesn’t want me to say “I don’t like” about anyone, even if I definitely do not like them.

 Unfortunately I don’t have a photo of Tillie in her beautiful gown. The New York Met has examples of gowns from 1910-1912, including one from 1910. An article on the history of Edwardian evening dress shows how the fashion changed over those few years. If Tillie was wearing the latest fashion, she would have worn one with an Empire waist like the example at the Met from 1911. The Met also includes a drawing from the time, showing the “bumps at the front.”
