While we have used stones as small as 6SS and as large as 48SS, the majority of our costumes are adorned with both 20SS and 16SS, and depending upon the project, with areas using 30SS, 34SS, and 12SS. Other adornments are used on our costumes in addition to Rhinestones; however, we only use Preciosa® and Swarovski® for the specifications listed in the sizing above.
