Get your Rhinestone Cowgirl on!  How do you make a silver metallic thread shirt better?  You add metallic fringe and leather stars of course! And that's what I did (oh yeah and added a few rhinestone studs).  I also added a strip of fringe and leather along the cuffs for that extra flare you know I love.
