So I don’t have a Herme’s Scarf, or the lovely YSL ring, BUT I have some larger cocktail rings I’ve never really worn that would look good in place of a broach on a scarf.
I DO have this vintage scarf I bought on ebay
and the ring was my grandmother’s.
I’m using a long rectangular scarf instead of a square. I threaded one side through the ring one way and the other side through the other way and tied a loose knot in the back so the ring was secure and wouldn’t fall off. I let the ends trail off the sides because the scarf did not start as a square like hers.
