I'm in love with these buttons with their central flat dome. Haute couture at will, these are noble buttons. They sublimate the garment and reflect the art of jewelry on the fabric. Just transition because these buttons are superb on a serge or a black tweed for example. Also favor thick or semi-thick fabrics will also be a plus.
Not that they are heavy, but more for their natural appearance, they will curl up perfectly on a soft fabric.
