Bouttoniers

What you just described sounds like a corsage.
Usually corsages just have more greenery than bouts.

Oh, really I thought that a corsage was one that went around the wrist. Maybe I need to update myself on the terminology...so then it would be okay for something like that then?

You can have a wrist corsage or a pin corsage....one that pins above the chest.
I think what you described sounds fine for a corsage.
I actually chose to do something similar at my wedding. I had the florist just do one large rose with lots of greenery and ribbon. I agree with you some corages just look too bulky and often get in the way.
Another alternative to the corsage is to do small bouquets for the mothers and grandmothers.
