I need a shrug that matches my dress?

I need a semi-formal dress for May Cowning, which is in a few weeks, and I recently bought my dress at Maurices. (seen here: a href="http://www.maurices.com/product/index.jsp?productId=11005374)." rel="nofollow"http://www.maurices.com/product/index.js…/a It is a spaghetti strap, however, and my school mandates that the sleeves have to be at least two inches or we have to have a shrug. I need a silver one that matches my dress seen on the link. It also needs to be under $40. Thanks!
