This hat is one of the pieces of which we're proudest. We used a silk and rayon velvet with a fluid drape and a luminous sheen. It appears with different colors depending on the angle, shifting between deep navy green to a fluorescent white green. This hat is especially fun to wear at night when the reflectiveness in the fabric really shows. The velvet also provides a textural component---in one direction it's silky smooth, but in the other direction it resists, almost like fish scales. Silk and rayon velvet.
