Hats or something for flower girls?

Hi Ladies,
I have four flower girls (all family) and one of them is currently going through chemo and has lost all her hair. She wont have any at the time of the wedding. I'm hoping that she will be well enough to still come on the day but I don't want her to feel left out.
Has anyone seen or have any ideas of something that I could get for her and the other three to wear on their heads that would mean that she wouldn't feel too different from them? Obviously a hair band etc would just draw attention from it but want to do everything that I can do make it all easier on her.
Here is the link to their dresses. They are a kind of champagne lace.
