We searched high and low for this hat and are so excited to offer it to our girlfriends in the fun colors for a bachelorette party, birthday party or girls' night out, not to mention as a fabulous costume accessory. The hat measures 6.5" across the width and 8 inches in length. It stands 5 inches tall and has a 2 inch brim piped around the edges.
