The bottom diameter is about 3" and can be expanded, & the top is a
couple coils of wire used as a clip..

Here's the packaging..
Place plastic ring inside of 'bra' with stem bent towards shoulder.
slip flower stem into loop.

(now we know how they stay there!)
I can't even the imagine today's awkwardness of presenting a girl with
