The Cure: Start Small
A cropped black pant, simple white silk tank, embellished lapel blazer, and a pop of color with a great Sam Edelman party pump is a superb way to start. You've got your sparkle and shine, a pop of color, and a tasteful ensemble that isn't over the top.
Second Opinion: BAM! Kick it up a notch
Obviously start with a cocktail dress that has it's own subtle sparkle, create interest with a sequined cardigan, play up the shine with patent platforms, and add your pop of color with a beaded clutch...if you're worried this is a little monochromatic, consider playing with textures and the level of shine. You want to stand out, but not be outlandish.
