I think it would look best on a model, but I agree that I would want one that hadn't been worn...so there, that's probably completely not helpful. Maybe you could do something completely silly like make it into a slingshot? Or hang it by fishing line, maybe skewed a little bit to look natural, and have a background of a groom just tossing it? (yeah, really hard to stage, I know...) Or, if you're artsy, have the background be a sketch of a bride so it will look like she's wearing it? (Maybe Photoshopped together for scale?) I'm picturing a vintagy looking thing. Then in your other pictures you could have it flat so they could really see what it looks like. Probably not helpful, but I had fun...hope it will spark some good ideas, anyway!
What about a bride model, but with it in her hands, pre-putting it on? Or in the groom model's hand before he throws it? If it's a close-up, it could be anyone's hands with a festive background, but would still give it some life, rather than just being flat.
Ok. I'm done now. Really. :)
