I bet whatever suits your personal aesthetic would be great. I don't know if we are allowed to post a link of the kind of thing I imagined is allowed. If you put "fabric rose" into Google images the first pic that comes up is one nice idea.
Ack, I wish I could edit my posts. I am terrible about proofreading, lol. I meant to say that a fabric corsage/rosette that could be used in the hair or as a pin would be cute. It would also make a cool bracelet. I like the idea of adding a very girly touch to a more masculine fabric.
