Typically people think of silver and gold sequins; why not try Forever21's sequin dress in plum--stunning!
If you're afraid of being a bit too sparkly, try just a touch of sequin--perhaps a sequin purse. New York and Company has lovely small cross-body purses in silver, gold, and RED: http://www.nyandcompany.com/nyco/browse/productDetailWithPicker.jsp?productId=prod4940003&categoryId=cat70158&FLCat=cat70094&productId=prod4940003&categoryId=cat70158&addFacet=1002%3Acat70158
