Gown in 4-ply silk crepe with 84 matching buttons and loops.  2012.  photo markmitchellburial.com

Each of these buttons starts with a 7/16"  wooden mold that is covered with a small circle of silk crepe to match the gown.  Tiny stitches are used to gather and tighten the circle from behind, so that the front and sides of the button are completely smooth.  This gown requires 84 such buttons to close the front and sleeves.  Matching loops are created from silk and padded with wool to take the place of buttonholes.
