According to millinery in the 1930's, brown-eyed susans are appropriate with white daises for a girl from 12-18, but altogether "too gaudy" for a middle-aged woman! Just a fun fact I thought you might like, out of a Women's Institute pamphlet. I was reading it because I have been making the flowers on the 1909 hat below. I'll have better photos soon, that was taken before it was finished. I made the roses using a Threads tutorial, which I guess they don't have online, but I found this one for a really lovely lotus flower.
On a much sadder note, our beloved Alexander McQueen died yesterday. He really blended costuming with fashion in a way quite unlike anyone else and he will be so missed.
