I have lots of suits and SC's, and was wondering if, instead of sewing boutonniere loops on all of them, there already exists a type of metal pin which could do the job. I hope I explain myself well, but I'm envisioning a kind of Greek letter Omega shaped pin, where squeezing the ends together slightly and letting them expand into the back of the lapel would secure it in place and the points would be out of sight by being "trapped" between / within the material of the lapel itself. Then there would be a little metal loop left hanging on the back of the lapel which could hold a small flower stem. Did I explain that at all well? Does such a thing exist?
