Emma Watson wore one bold piece of jewelry with a strapless dress -- I think it's a good look for her, a combination of trendy and classic.
Juicy Couture offers a riveted leather cuff with a similar look. It's available in two colors. (Buy Direct)
And I'll send you to Etsy again to search for hand-crafted leather cuffs. When I looked, the search produced over 1,300 results. It's a mixture, but plan to spend some time browsing because you'll find lots of good looking bracelets to consider.
